Re: *NOMAIN procedure with display file

[Bryce Martin <BMartin@xxxxxxxxxxxx>]

Hey Lim,

Nice catch.  That worked like a charm.  In a normal program it doesn't 
matter, only in the procedure.  I didn't realize the procedure scoped so 
strictly like that. 

Just for those wondering, this was just an example of something that was 
happening in a larger program I'm writing. So I didn't bother trying to 
use the variables in the code, this code was just to isolate the problem.

Thanks again to all.


Thanks

Re: *NOMAIN procedure with display file






Haven't had a chance to test it yet.  But a quick glance of the code
seems to indicate that the problem is probably cause by the fieldDS data
structure contains field1/2/3.  Remember that fields in the file (At
aleast up to V5R4) are considered global variables.  If you re-defined a
global field in a procedure.  The field in this procedure override the
global field.  So... If you move you fieldDS to the global section, I
think, everything should work fine.  Just a guess..
