Command Line Options
Options:
M - Differences are displayed but memory relative
addresses starting at 100 hex are used.
T - Differences are tested for but not displayed.
Flow control register 9 is set depending on
the test results as follows:
REG 9 = 0 if both files compare.
REG 9 = 1 if file1 is not found.
REG 9 = 2 if file2 is not found.
REG 9 = 3 if files do not compare.
