20* Purpose
21* =======
22*
23* PCGSEPREQ performs one request from the input file 'SEP.dat'
24* A request is the cross product of the specifications in the
25* input file. PCGSEPREQ prints one line per test.
26*
27* Arguments
28* =========
29*
30* NIN (local input) INTEGER
31* The unit number for the input file 'SEP.dat'
32*
33* MEM (local input) COMPLEX ARRAY, dimension MEMSIZE
34* Array encompassing the available single precision memory
35*
36* MEMSIZE (local input) INTEGER
37* Size of MEM array
38*
39* NOUT (local input) INTEGER
40* The unit number for output file.
41* NOUT = 6, output to screen,
42* NOUT = 0, output to stderr.
43* NOUT = 13, output to file, divide thresh by 10
44* NOUT = 14, output to file, divide thresh by 20
45* Only used on node 0.
46* NOUT = 13, 14 allow the threshold to be tighter for our
47* internal testing which means that when a user reports
48* a threshold error, it is more likely to be significant.
49*
50* ISEED (global input/output) INTEGER array, dimension 4
51* Random number generator seed
52*
53* NTESTS (global input/output) INTEGER
54* NTESTS = NTESTS + tests requested
55*
56* NSKIPPED (global input/output) INTEGER
57* NSKIPPED = NSKIPPED + tests skipped
58*
59* NNOCHECK (global input/output) INTEGER
60* NNOCHECK = NNOCHECK + tests completed but not checked
61*
62* NPASSED (global input/output) INTEGER
63* NPASSED = NPASSED + tests which passed all checks
64*
65*
66*
67* INFO (global output) INTEGER
68* 0 = test request ran
69* -1 = end of file
70* -2 = incorrect .dat file
