Re: Global variables in a Service Program

I sometimes create service programs with nothing more than exported data 
structures, so they can be bound to other programs and service programs in the 
same activation group, and share the same data.

Subject: Global variables in a Service Program 

Quick question.  I've got some variables and constants that I'd like to 
make global but I'm concerned about scope.  Basically, I have three 
service programs that all use a couple of the same fields, i.e. errMsg, 
cmdLen, myCmd, etc..  Do I put them at the top of each svcpgm module or in 
a separate copybook?  And would there be issues with duplicates when all 3 
svcpgms were bound into one rpgle pgm?

Thanks,
