Access command definitions, files, and procedures

To access command definitions or files from a CL program, the command definitions or files must exist at creation time of the program and must exist when the command that refers to them runs.

Two requirements exist for creating a CL program from source statements that refer to command definitions or files.

The objects must exist at creation time of the program.
The objects must exist when the command that refers to them runs.

This means that if you use the Declare File (DCLF) command, you must create the file before creating a program that refers to the file.

Access command definitions
Access to the command definitions occurs during program creation time and at command run time.
Access files
A file must exist when compiling a CL module or OPM program that uses it.
Access procedures
A procedure that is specified by Call Bound Procedure (CALLPRC) does not have to exist at the time a module that refers to it is created.
