Replacing a HANDLE with EIBRESP

1. Where do I see the performance improvement when I remove HANDLE condition and replace it by EIBRESP check?

2. Where do I see the performance improvements when I remove PROGRAM IS INITIAL from a called program?

3. When I convert a dynamically called program to a PERFORM (paragraph), where do I see the performance improvements?

I can only answer the first question. The others are COBOL (I assume) so look in the LE books for information on them.

You will get a very small performance improvement by not using XC HANDLE as no stacking function is executed. Anyway I think that most people would check the EIBRESP directly. Nevertheless, use of XC HANDLE might be more familiar to someone coming from a Java background as this gives a sort of throw/catch function.
