What does the Xpediter manual tell you?

If you can't find what you're looking for in the XPED documentation, then perhaps you need to contact Compuware Technical Support?

you can not go backwards in xpeditor. do you expect the outcome of executed instructions to be the reverse?

going backwards would serve no purpose.
asking you why would serve no purpose.
I don't really care why you don't understand computers.


use a goto to re-start execution at a point that you wish to monitor.

you obviously need to prep the values of variables.

Dear Prabakar,

Flip through the manual for "Monitor" and "Reverse".

Thanks
Ajay

It depends on which Xpediter you are talking about. Xpediter/TSO for BATCH programs does have the ability to step backwards. The thing to keep in mind is that you are simply stepping backward thru a log of where you have been. So you can't change any of the variables or the execution path.
Xpediter/CICS for online programs does not have this ability.

To use Xpediter/TSO to step backwards, you need the MONITOR and REVERSE commands.

Start a new session and use MONITOR ALL (monitor all modules)
GO will get you to an abend statement,
REVERSE
F9 to singel step backwards
REVERSE (will switch to FORWARD)
RESUME (will get you back to the current execution pointer)
DELETE MONITOR ALL (to stop monitoring)

***monitoring is “expensive” because it has to keep track of all of the variables in Working Storage as they are at every line of code. So only use it when absolutely necessary and turn it off when you are done.
