PARAM Command

The PARAM command creates a PARAM message in your current environment.

When a process compiled by the compiler begins to execute, the run-time routines

automatically request the PARAM message and use its contents to set the options

defined for HP COBOL. Application code within the program can also use the SMU

procedures to copy the PARAM message into the Working-Storage area and examine

it for additional parameters that apply to the program. Further, the program can

manipulate the saved parameters and cause them to be passed to any processes it

initiates using the CREATEPROCESS or CLU_PROCESS_CREATE_ routine.

25> == Run the loadfile,

26> == designating NEWINP as

27> == the IN file (thus

28>RUN PROG3 /IN NEWINP,OUT NEWOUT/ == equating it with the

29> == fd-name INPUT-FILE)

30> == and NEWOUT as the OUT

31> == file (thus equating it

32> == with the fd-name

33> == OUTPUT-FILE).

Note. PARAM commands for files in a user library are ignored.
