I like to know is there any generic way to handle the errors in a REXX program like in VB ...On error .

I'm doing lot of functionality inside the REXX program like allocating the dataset, deleting the datasets, calling PL/I programs etc....so, I want to track on any kind of errors immediately. If there is any error, my program should halt with proper error message.

Thanks in Advance

I would say that you check for "RC" which gets populated automatically after the execution of any REXX command. If it is not equal to zero, then tere is a warning or error. You can get the meaning of the return codes(they are numeric) from the REXX manual of the IBM book manager.

Now I will narrow my query.

I used to check for RC and also used OUTTRAP. But it still displays messages which starts with IRX.

Is there any stop/block the error messages displayed directly on the screen. I want to customize the error messages being displayed by mainframes.

Can I have a sample code of SIGNAL ON ERROR or SINGAL ON HALT.

Where are this statements being placed. Either on the first line while starting the rexx routine or check it before allocating or deleting the statements.....

Thanks in advance.

OK. Got it. Basically you are trying to handle the error conditions that are automatically checked by the REXX interpreter.
The REXX interpreter checks for the following 6 conditions -
SYNTAX
NOTREADY
ERROR
FAILURE
HALT and
NOVALUE.

If you don't want the REXX interpreter to handle these conditions and initiate the default action but want to handle these conditions yourself, then code the following as the first line of your REXX routine -
