RE: Seeking adivce -- RPG400-L

Are you talking about a data area or a data queue?  With a data queue you don't 
have to worry about unique entries.  They are placed on the queue in the order 
written even if they have identical information.  If you replace the file this 
would be my choice for a replacement.

You mentioned not reinventing the wheel in your first post.  Using a data queue 
means changing every program that currently writes to the work file.

Hmm.. .I never thought of that... maybe use their username and the
time to create the data area. I was thinking a file, but that is hard
to do dynamic. I will have to look more into reading and writing to a
data area, but I think that would work. Thanks for the suggestion.

I am still open if you feel there is a better way!
