How to Execute a REXX Program from Option 2.4

The REXX Execute Entry panel appears when you enter any of these commands from the REXX Source Program List:

• The EXECUTE primary command
• The OI line command
• The OX line command

Following is a sample REXX Execute Entry panel. Use the panel to specify arguments to be passed to your REXX program. You may specify arguments of up to 120 characters in length. You may also specify an initial TRACE value for the execution of the program. Pressing Enter executes the program and pressing End cancels the execution.

REXX Execute - Entry panel --- MSI1 --- S Y S V I E W -------- Subsystem OPSS
COMMAND ===>
   List any ARGUMENTS to be passed to the program ARGT
    ----+----1----+----2----+----3----+----4----+----5----+----6
    ----+----7----+----8----+----9----+---10----+---11----+---12
   Specify initial REXX TRACE value:
   (default to none - valid values are A,C,E,F,I,L,N,O,R)
Press ENTER to process or END to cancel.

You may specify the following TRACE values on the REXX Execute Entry panel:

A

Trace all

C

Trace host commands before execution only

E

Trace host command errors

F

Trace host command failures

I

Trace intermediate results

L

Trace labels only

N

Trace normal

O

Trace off

R

Trace results

Although you do not have to specify an initial TRACE value, doing so provides you with the ability to do debugging without having to add a TRACE statement to your OPS/REXX program. This can be especially useful for debugging pre-compiled programs. You do not have to go back and edit the source version of the program to add a TRACE statement to perform debugging.

Note: Any TRACE statement that is in your OPS/REXX program overrides the TRACE value that you specify on the REXX Execute Entry panel.
