OPSSETV Invoked as a REXX Function

In addition to invoking OPSSETV as a TSO command, you can invoke it as an OPS/REXX or TSO/E REXX function. The function will have a single argument equal to the OPSSETV TSO command syntax. The value returned by the function will be either 1 (for REXX true) or 0 (for REXX false). The CA OPS/MVS product sets the OPSRC variable to the same return code that would have been generated if you had invoked OPSSETV as a TSO command.

Examples: OPSSETV

• This example sets the variable to the specified value if the current update counter is 2. If the counter is not 2, the update fails:

  OPSSETV GLOBAL0.XYZ (THIS IS A TEST) TOKEN(2)
  

• This REXX function updates a substring of the variable beginning at position 10 in the current value of the variable. If the current value is ABCD, positions 5 through 9 of the variable become blanks. The vrc variable is set to 1 (for REXX true). The OPSRC variable is set to the same return code that would have been set if you had invoked OPSSETV as a TSO command:

  vrc = OPSSETV('GLOBAL0.XYZ (WORKS IN REXX) OFFSET(10)')
