Hi Scott,

An example from work today.

I was told to find out "how is the outq assigned to the debit packing slip"

First stop to find out was the print pgm. I scan the code and find no
OVRPRTF code.

Next I look at the backround processor cl which calls the print pgm. It has
an override, but it gets the override value from the *Lda.

A search of the cl pgm shows the *Lda being loaded with data from the data
queue which feeds the bp.

Now I have to find the interactive pgms with send the "print debit packing
slip" msg to the dtaq.

I find that those pgms load the *Lda with info from different sources.

etc, etc.

That is tough to encapsulate.

If it was all pgm call based from start to finish, no BP, I could ask a user
to run the print option, put them in StrSrvJob debug, and step the code to
find out what I needed to know.
