There are several shell or DCL commands for running CONGEN. In addition to these commands, on Unix systems, CONGEN can be executed directly by typing congen.
RUNCGnwill assign filespec.INP to FOR005 and filespec.OUT to FOR006 and then run CONGEN. The -i and -n integer options are not permitted on VMS. On UNIX, it will run CONGEN with standard input and output being set to filespec.inp and filespec.out. The nice command will be used with an argument of 4 to lower the runtime priority. The option, -i, specifies that interactive priority should be used. The option, -n integer, specifies an alternate nice value.
