Re[2]: Environment variables

[eric.delong@xxxxxxxxxxxxxxxxx]

     Well, we were wanting to use CL ADDENVVAR in out initial program 
     (CLP). Do I need to write a little rpg pgm to set as well as get? 
     I'd prefer to use the CL command if possible.
     BTW, I don't suppose you have prototype on this? <g> 
     Oh. You say these are ILE service program calls... Will I have 
     problems if I'm using DAG for this program? (Sorry, still pretty 
     green in ILE).

They are callable from ILE/RPG.

Be very careful which one you use. There are two different putenv/getenv
pairs exported from two different system supplied *SRVPGM's and they are not
compatible with each other.

The symptoms you will see if you get a mismatch are that you will put
env.vars successfully, but on getting them, you'll see empty values - even
though you know they are there !!

Just ensure you use the same 'set' in all your pgms.
