Maybe I wasn't clear enough Jay -

Take RDi outline via for example. Click on a variable name in the outline and ALL references to the that field show up. The ones that change the content are marked with (M) - click on that (M) line to see the actual instruction.

The X-Analysis tool set is explicitly designed to handle exactly this scenario. It goes one-step further than RDi in that it provides a complete data flow for any field. From the first point at which that data is entered into he system to any point where is is used and/or modified.

What more do you need?

jon - thanks

but I'm referring to after you use those tools... say you know that pgmA
puts data in table/column, but pgmA is a 20 year old monolithic beast with
6K+ lines of code... and customer wants to know the calculations involved
to produce the data in that field :)

That pgm may have 50+ subroutines
That pgm may have repeated GoTo's..
etc...

Use one of the number of available commercial tools that can do this. e.g.
Abstract/Probe, Hawkeye, the X-Analysis tool family and others.

If you use RDi it will build a where used/defined/changed list in the
outline view. That's what I use most of the time - but it only works
within a program - not across program tools like the tools do.

So being in the legacy world for 20+ years and working with ancient
cobol/rpg code that a single pgm can span 10k+ lines of code, I still
have
not found an efficient way to answer clients requests of "how is the data
arrived at in this table/column?" Aside from a whole lot of time, effort
and grunt work.

How do others handle these requests?
