If RESULT( K ) > THRESH, then the K-th test 00061 * did not pass the threshold and a message will be printed. 00062 * Not modified. 00063 * 00064 * IOUNIT - INTEGER 00065 * On entry, IOUNIT specifies the unit number of the file 00066 * to which the messages are printed. 00067 * Not modified. 00068 * 00069 * IE - INTEGER 00070 * On entry, IE contains the number of tests which have 00071 * failed to pass the threshold so far. 00072 * Updated on exit if any of the ratios in RESULT also fail. 00073 * 00074 * ===================================================================== 00075 * 00076 * ..
