--- no data are required
-- Error --
If possible, the requirements on the data that must be satisfied are
given explicitly (>< means "not equal"). No entry means that no check
is made for errors. If there is insufficient room for listing them, then
reference numbers of errors are separated by a semi-colon. The following
is a key to the reference numbers:
1. Components to be changed must not have an index that is greater than
the current dimension.
2. The command must be a valid MICROSCOPE command. If it is not
recognized you will be prompted for another command to be helped on.
Typing any valid command will get you some information on it and will
then return you to command mode.
3. The list must contain only points in a legal format. If illegal
characters are encountered, an error termination of the command will
occur. Also, the index number must not exceed the number of points in
the list. If it does, the program will reach the end of the file
containing the list, and the precise action after that depends upon the
computing system.
-- Screen --
activ the command activates the screen
deactiv. the command deactivates the screen - i.e. the GO or FORCE
command must be given before the computation proceeds.
For some commands, there is a check if the newly input
datum is identical with the old one, in which case the
screen remains active.
immediate If the screen is active then the effects of the command
are incorporated before the next command is requested
pending If the screen is inactive, this command will keep the
graphical display on the screen, even if computations are
pending.
--- The graphical and numerical display, and the screen status
are not changed. Notice, however, that the actual screen
display may be destroyed by error messages or help information.
The next display changing command (or RSCREEN) will then
refresh the screen.
ACCENT mark derivative with asterisks TOGGLE k -1<k<7 immediate
The graph of any derivative can be accentuated, with asterisks in the
alphanumerical display, or by marking it with symbols twice their normal
size in the PLOT79 drawings. This option is off by default, and is
turned on or off for the specified derivative by the ACCENT command.
In the alphanumerical display, the graph of any accentuated derivatives
overwrites the graphs of all other derivatives. No information about
any accentuation is contained in the numerical display, so if several
graphs are accentuated, then they may become indistinguishable in the
graphical display (although not in the PLOT79 display). ACCENT also
turns the graph of the accentuated derivative on, so that it is
unnecessary to use DGRAPH.
For more information see section 4.5 of the manual.
C1CROSS read 1st component of cross direction C1 C><0 deactiv.
This command replaces the first component of the cross direction with
the number read from the input device, leaving the other components
unchanged. This is useful for correcting errors. If cross
differentiation is currently inactive, it is activated by C1CROSS, and
its order is set to 1 by default.
For more information see section 4.12 of the manual.
C2CROSS read 2nd component of cross direction C2 C><0;1 deactiv.
This command replaces the second component of the cross direction
with the number read from the input device, leaving the other components
unchanged. This is useful for correcting errors. If cross
differentiation is currently inactive, it is activated by C2CROSS, and
its order is set to 1 by default. If the current dimension is 1 an
error will result.
For more information see section 4.12 of the manual.
C3CROSS read 3rd component of cross direction C3 C><0;1 deactiv.
This command replaces the third component of the cross direction with
the number read from the input device, leaving the other components
unchanged. This is useful for correcting errors. If cross
differentiation is currently inactive, it is activated by C3CROSS, and
its order is set to 1 by default. If the current dimension is 1 or 2 an
error will result.
For more information see section 4.12 of the manual.
CCHANNL change channel number ic,nc 4 ---
This command is used to change those channel numbers that are input
parameters of the routine MCRSCP. The first parameter describes the
channel to be changed, the second is the new channel number. The
channel types are:
1. Input Device
2. Output Device
3. Graphics Device
4. Recording Device
5. Restart Device
The logging device and the three point loading devices can be
changed by using the commands LOG, RCROSS, RPOINT, or RDIRCTN. The
current channel numbers can be viewed in the last line of the numerical
display, in the sequence:
1. Input Device, 2. Output Device, 3. Graphics Device, 4. Help Device,
5. Recording Device, 6. Restart Device, 7. Logging Device, 8. Point
Loading Device, 9. Direction Loading Device, 10. Cross Direction Loading
Device.
The Help Device number cannot be changed, and you should take care
not to overwrite the help file.
For more information see section 4.13 of the manual.
CDIRCTN read direction of cross direction C C><0 deactiv.
This command reads the new cross direction from the input device. If
cross differentiation is currently inactive, then it is activated, its
order is set to 1 by default, and the value of the cross differentiation
parameter is set equal to the current value of the discretization
parameter h. A zero cross direction will result in an error.
For more information see section 4.12 of the manual.
CHVALUE read ch for cross differentiation ch 5 deactiv.
This command reads the new value of the cross differentiation
parameter ch from the input device. If cross differentiation is
activated by setting the cross direction it is unneccessary to give this
command as ch is set automatically to the value of the current
discretization parameter h. Future changes of h have no impact on ch to
maintain efficiency. The CHVALUE command is the only one allowing to
change the value of ch while cross differentiation is active.
For more information see section 4.12 of the manual.
CORDER read order of cross derivative k -1<k<7 deactiv.
This command reads the new order of cross differentiation from the
input device. Setting the order equal to zero deactivates cross
differentiation. If no cross direction is set then it assumes its
default value which is a vector with 1s in all of its components.
For more information see section 4.12 of the manual.
CWINDOW change window width by factor SIGN m m=0 immediate
This command multiplies the current window width with the specified
factor if is positive, and divides by its absolute value if it is
negative. This is accomplished by adjusting the discretization
parameter h and leaving the display interval fixed. If h is to be kept
fixed (e.g. because it cannot be decreased on account of round-off
errors) then the ZOOM command should be used instead. However, CWINDOW
is more efficient in terms of function evaluations.
For more information see section 4.8 of the manual.
D1CHDIR read 1st component of dir. of inv. D1 D><0 deactiv.
This command reads the new first component of the direction of
investigation, leaving the others fixed. This is useful for error
corrections.
For more information see section 4.7 of the manual.
D2CHDIR read 2nd component of dir. of inv. D2 D><0;1 deactiv.
This command reads the new second component of the direction of
investigation, leaving the others fixed. This is useful for error
corrections. If the current dimension is 1 then an error will result.
For more information see section 4.7 of the manual.
D3CHDIR read 3rd component of dir. of inv. D3 D><0;1 deactiv.
This command reads the new third component of the direction of
investigation, leaving the others fixed. This is useful for error
corrections. If the current dimension is 1 or 2then an error will
result.
For more information see section 4.7 of the manual.
DCENTER draw center of graph. display TOGGLE --- --- immediate
This command turns the center mark (a plus sign in the center of the
graphical display or a horizontal line in the PLOT79 display) on or off.
It is off by default.
For more information see section 4.5 of the manual.
DGRAPH draw graph k -1<k<7 immediate
This command flags the graph of the specified derivative for
plotting. The graph can be erased using the command EGRAPH. Tangential
derivatives of 0th through 6th order can be drawn or erased. By default,
only the graph of the display function itself is drawn.
For more information see section 4.5 of the manual.
DIVIDE divide h by integer m SIGN m d><0 immediate
This command divides the current value of the discretization
parameter h by the specified positive integer factor, leaving the window
width fixed. If the factor is negative, then h is multiplied rather
than divided. The division is most efficient if the factor is a power
of 2.
For more information see section 4.8 of the manual.
DMNSN read dimension v of domain v 0<v<4 deactiv.
This command reads the number of independent variables from the input
device. It also resets the point of examination, the direction of
investigation, the cross direction, and the order of the cross
derivative to their default values. The default dimension is 2.
For more information see section 4.5 of the manual.
DOUBLE double h --- --- immediate
This command doubles the current value of the discretization
parameter h, leaving the window width fixed.
For more information see section 4.8 of the manual.
DSCALE draw scale in graphical display TOGGLE --- --- immediate
A horizontal scale can be drawn in both the graphical and the PLOT79
display. In the graphical display, the scale gives the distance in
columns from the point of examination. This is useful for shifting the
graph (using SHIFT) or reading off numerical values (using TYPE). In
the PLOT79 display, the scale gives the Euclidean distance from the
point of examination. This option is turned on or off by DSCALE, and is
off by default.
For more information see section 4.5 of the manual.
DXAXIS draw horizontal axis TOGGLE --- --- immediate
A horizontal axis (i.e. a row of minus signs in the graphical display
or a single straight line in the PLOT79 display) can be drawn. This
option is turned on or off using DXAXIS, and is off by default.
For more information see section 4.5 of the manual.
EGRAPH erase graph k -1<k<7 immediate
This command erases the graph of the specified derivative from the
graphical display. The graph can be flagged for plotting using the
command DGRAPH. Tangential derivatives of 0th through 6th order can be
drawn or erased. By default, only the graph of the display function
itself is drawn.
For more information see section 4.5 of the manual.
EXIT return to calling program --- --- deactiv.
This command leaves MCRSCP vial a FORTRAN RETURN statement. It is
possible to call MCRSCP again with the current settings of most of the
parameters intact. However, peculiar displays may result if screen
parameters are altered between calls to MCRSCP. The recommended way of
calling user defined routines while in MCRSCP consists of using the
command USER.
For more information see section 4.9 of the manual.
FLIP replace d by -d TOGGLE --- --- immediate
The FLIP command can be used to replace the current direction of
investigation d by -d. This may be useful to disentangle the graphs of
derivatives that otherwise overwrite each other. No new evaluations of
the trial function are needed.
For more information see section 4.5 of the manual.
FORCE recompute everything --- --- activ
This command computes new derivatives and a new display discarding
any previous evaluations of the trial function. This is useful if
the trial function itself has been changed (e.g. by using the command
USER). If, on the other hand, previous evaluations are still valied
then the command GO should be used instead.
For more information see section 4.9 of the manual.
GO compute whatever is needed --- --- activ
This command computes new derivatives and a new display making use of
previous evaluations of the trial function. If these are no longer valid
(e.g. when the trial function has been changed) use the FORCE command
instead.
For more information see section 4.9 of the manual.
HALVE halve h --- --- immediate
This command halves the current value of the discretization parameter
h without altering the curren window width.
For more information see section 4.8 of the manual.

IINTVL read endpoints of line of investig. A,B A><B deactiv.
This command defines simultaneously the new point of examination,
direction of investigation, discretization parameter, and display
interval by the endpoints of the domain of the graphical display. The
first point corresponds to the left end of the display, the second to
the right end. The two points must be distinct. The two endpoints must
be typed on separate lines.
For more information see section 4.6 of the manual.

MULTPLY multiply h by factor m SIGN m m><0 immediate
This command multiplies the current value of the discretization
parameter h by the specified positive integer factor, leaving the window
width fixed. If the factor is negative, then h is divided rather than
multiplied. The multiplication is most efficient if the factor is a
power of 2.
For more information see section 4.8 of the manual.
NEWS print the news --- --- ---
This commands prints any available news on the output device. The
first line of the news is printed when MCRSCP is first entered. This
facility may be used by your system manager to inform you of recent
changes in MICROSCOPE or similar purposes.
For more information see section 4.10 of the manual.
NORMAL turn normalization of D on/off TOGGLE --- --- deactiv.
MICROSCOPE computes either standard directional derivatives (the

RSCREEN refresh screen --- --- pending
This command has two applications:
On an active screen, it refreshes the screen image, e.g. after it has
been destroyed by a system message or by some MICROSCOPE HELP
information.
On an inactive screen, it prints the current state of the graphical
and the numerical dispaly without doing any computations. In that case,
the graphical and the numerical display may be inconsistent. This
condition is indicated by the flag "GO pndng" in the numerical display.
For more information see section 4.5 of the manual.
RWIND rewind device nc nc --- ---
This command rewinds the device with the given number. It can be
used to read a sequence of commands for a second time or to overwrite
information that was generated earlier and is no longer needed.
For more information see section 4.13 of the manual.

(N = 1, D = 10, ETA = 1, no exponential is added)
For more information see section 4.9 of the manual.
SHIFT shift point of examination is --- immediate
This command shifts the current display by the given number of
columns. A positive shift corresponds to a shift to the right. There
is nor restriction on the number of columns, in particular it may exceed
the number of columns in the display.
For more information see section 4.6 of the manual.
STORE store current parameter settings --- --- ---
This command stores all current parameter settings on the Restart
Device. Any subsequent STORE command will overwrite that information.
So if several configurations of a session must be saved, then the
Restart device must be assigned to a different file for each
configuration. This can be accomplished either by the commands CCHANNL
or USER.
For more information see section 4.9 of the manual.
TCENTER type value of k-th derivative at center k -1<k<7 ---
This command prints the value of the specified derivative at the
point of examination. Only derivatives that have actually been computed
can be so displayed.
For more information see section 4.5 of the manual.
TNOTE take a note on recording device --- --- ---
This command copies subsequent input onto the recording device,
documenting e.g. any screen images that have been deposited there by the
OUTPUT command. The documentation is terminated by the upper case "EC"
(End Comments) in the firs two columns.
For more information see section 4.11 of the manual.
TYPE Type value of derivative at some point k,is -1<k<7 immediate
This command prints the value of the k-th derivative at the is-th
column in the display. The value is = 0 corresponds to the point of
examination.
For more information see section 4.5 of the manual.
UNDO undo previous parameter changes --- --- ---

-4- The value of the discretization parameter h
-5- The window half width w = h/s
-6- The number of independent variables
-7- Marking of the center point
-8- Drawing a horizontal scale
-9- Drawing a horizontal scale
-10- The selection of graphs plotted
For more information see section 4.9 of the manual.
USER enter user mode --- --- ---
This command calls the user defined subroutines SUBUSR which can be
used for various purposes. If it changes the trial function then care
should be taken to use the command FORCE instead of GO.
For more information see section 4.15 of the manual.
WAIT make program wait for GO or FORCE com. --- --- deactiv.
This command suspends all computation until the next GO or FORCE
command is given. This is useful if several changes are to be made and
it is inconvenient to wait until they have been incorporated into an
active screen.
For more information see section 4.9 of the manual.
ZOOM change window width by factor SIGN m m><0 immediate
This command multiplies the current window width with the specified
factor if is positive, and divides by its absolute value if it is
negative. This is accomplished by adjusting the display interval
and leaving the discretization parameter h fixed. This is useful if h
cannot be decreased because of round-off effects. However, whenever
possible the more efficent command CWINDOW should be used instead of
ZOOM.

MICROSCOPE News v. 1: A Primer on MICROSCOPE
Welcome to MICROSCOPE.
If at any stage you are getting tired of this summary you can abort
it by typing a period (followed, like everything else in MICROSCOPE by
a carriage return, see below).
It is assumed that you know what you want to use MICROSCOPE for and
that you only need to know how to go about it. To make full use of
MICROSCOPE you really should obtain a copy of the manual which is
distributed with the MICROSCOPE package and should be available from
your system manager. If for some reason you can't get a hold of one,
contact Peter Alfeld, Department of Mathematics, University of Utah,
Salt Lake City, Utah 84112, Tel. 801-581-6842. I'd also be glad to hear
of your comments or suggestions.
The following is an excerpt from section 3.2 of the manual. It
describes the structure of the interaction with MICROSCOPE:
3.2 The Command Mode
The MICROSCOPE prompt is of the form:
n >>
where n is the number of the command to be given. It starts at 1 and is
incremented by 1 after each command.
A MICROSCOPE command is a string of at least two letters and
digits. However, only the first two characters are significant and
recognized by the parser. They must be entered in the first two columns
immediately following the prompt. On an active screen, this will be in
the same line as the prompt, on an inactive screen, or in the scrolling
version, on the next line. Blank spaces are significant. (MICROSCOPE
simply reads the command using a 2A1 format.) The remaining columns can
be filled with arbitrary characters. They are not read or processed by
MICROSCOPE. This is sometimes useful for including comments in a
program. A command line is terminated by pressing the RETURN button.
If the command is not recognized, MICROSCOPE prompts for another one.
After a command you will be prompted for the appropriate data
(if any are needed). The prompt is specific to the commands.
The dimension of the vectors is identical to the number of
variables of the trial function. (The default is 2, see section 4.18
for a listing of all defaults). Numbers are processed by an internal
parser and are essentially format free. The following distinctions and
restrictions apply, however:
- Blanks are ignored. For example "1 2" is considered the
single integer 12.
- Numbers on the same line must be separated by commas.
- Numbers can also be separated by writing them on separate
lines (omiting the comma).
- If two vectors are requested, then the second vector must
start on a new line .
- When a single number (Integer or Real) is requested, then an
empty string (obtained by just pushing the RETURN button) is considered
to mean zero. This is particularly useful when a zero entry implies
that a submode (see the descriptions of the PLOT and the USER commands
in sections 4.14 and 4.15 respectively) is to be exited.
- When two integers are requested, then either one or both can
be represented by an empty string. (The only command for which this
feature is useful is TYPE.)
- Floating Point numbers (like 1.0E-12 or 1D-4) are processed
correctly.
- Floating Point numbers may also be represented as integers.
After receiving the data, MICROSCOPE processes the command and
the data. If the screen is active, then the command is carried out and
the alphanumerical display is updated, otherwise the next command is
prompted for.
If a command is not recognized by MICROSCOPE, then a message
will be printed to that effect and a new command will be prompted for.
If data are requested, and a number is not recognized, then you will
have a chance to correct your input. However, if data are syntactically
correct, but otherwise meaningless (e.g. you request the graph of the
117th derivative), then the command will be aborted and a new command
will be prompted for.
There are currently 63 commands which divide into 11 major groups.
You can obtain a listing of them by giving the command LIST, a brief
description of all of them by HSUMRY, and detailed help on an individual
command by HELP.
Good luck, you are on your own now ...
