CCM CCM is an RSX utility for comparing DOS CIL files created by CILUS. It is not a terribly bright utility, so it may not give an accurate report of the differences. But it will bring attention to those modules within the CIL, which do need further checking. The command line format is as follows: CCM [/-SP]=<1st CIL>,<2nd CIL> where, - is the report listing. Defaults to *.CMP. <1st,2nd CIL> - are the CIL files. Defaults to *.CIL. CCM will require further indirect commands as follows: C [:] - sub modules to be compared. The 2nd name is not needed if same as the 1st. P - purge all indirect commands. E - signals end of commands and starts execution.
