RE: Passing data structure to batch job

Jon,

Wow, I've never seen uses of the LDA like that before! I agree that whoever
came up with that idea should be drawn and quartered.

That wasn't the scenario I had Jerry. In my case the LDA was being used to
contain variables that customized the software for the user. It was set when
they signed in and used throughout the application. Trouble was nothing
stopped you from calling other apps from the command line within the primary
app. The called app looked to the LDA to see if it had already been
initialized for its use. Found a flag that indicated the data had been
populated and then blew sky high because the data in the LDA wasn't what it
expected because it was actually residual from the first app.

I've seen these problems, too, Jon. Always when the programmer
hard-coded the definition of the LDA in the program. That is, the LDA was

"flexible"

for each procedure.

On the other hand, I have never had an issue with using the LDA
because the definition is defined in a copy book so it is always the
same regardless of which program is using it.

That said, I use it only for passing things like report selections
from one program to another, not data.
