Example: Function

A sample function that can be used under TSO/E REXX and CA‑GSS is provided in the CAW0JCL(BYSSFUN) data set member. When executed, it takes the following actions:

• Issue the following as SAY output:
  • User ID
  • Argument strings, if any
  • Stack contents, if any
• Place the string, NEW VALUE OF "SAMPLE" VARIABLE, in the SAMPLE variable.
• Return the string, THIS IS THE RETURNED RESULT STRING.

You can use the following REXX EXEC to check the operation of the BYSSFUN function:

queue 'stack_record_1'
queue 'stack_record_2'
queue 'stack_record_3'
rslt = BYSSFUN('arg_1',,'arg_3')
say 'returned string:' rslt
say '"sample" variable:' sample
