Re: pointer problem

David,

Frankly, pointers aren't a good area for experimentation. You need to fully understand what you are doing. It needs to be perfectly clear in your mind what's happening -- because if it isn't, you are unlikely to have code that works properly.

Incorrect use of pointers will often lead to bugs that don't show up in testing, but fail sporadically in production. Often at the most inopportune times.

Consider eliminating the pointer logic from the program.

Help, out of my depth here :

At this line :

C CLEAR gIstDS

I'm getting RNQ0222 Erreur parameter or pointer.



gIstDs is declared in a copybook.

D gIstDS DS QUALIFIED BASED ( Ptr_IstDS )
D gIstDS zones ....
D


D Ptr_IstDS S * INZ



This must be obvious to someone used to pointers!

Thanks
