Passing values to a procedure with logic

For procedures with logic, use the ARG option on the RUN PROC command to pass arguments, or values, to a procedure with logic. You can also use the ARG option to pass values between procedures.

Use the ARG option when you are running a procedure that contains a REXX PARSE ARG statement or ARG statement, as in the following figure.

Figure 1. The ARG option passes values to a procedure with logic.

 PROC               WILDE.SHOW_ARGS                      MODIFIED    LINE 1
 
 /************************************************************************/
 /* This procedure shows you how to use the 'ARG=' option on the RUN     */
 /* PROC command.                                                        */
 /************************************************************************/
 parse upper arg query_name form_name
 "RUN QUERY" query_name "(FORM="form_name

The RUN command for this procedure is:

RUN PROC SHOW_ARGS (ARG=(query_name form_name)

In this command, query_name and form_name are REXX variable names that describe the parameters being passed to the procedure with logic; they contain the object names for a query and a form, respectively. Using these variable names allows you to reference the parameters that were passed to the procedure with logic.
