Re: Determining which fields are updated or written in a program

Hi Eric

Some tools might recompile, as others mentioned. But they also go direct to source and analyze lines close to other lines, as well as follow variables and parameters through their calls. Yes, you could do it yourself - do you have that much time?

My thought was that if those tools can do it, so can I. They can't be recompiling all programs as a part of their tools. I should have access to the same stuff that they are using, right? Regarding recompiles, what if the programs have to have some OVRDBF done before the compile is done...

I think the only way to really get everything is to use a 3rd party app
like
Total or Abstract. They have had to write a lot of code to figure this
out.

Alan,
I was hoping that I did not have to recompile (potentially) hundreds of
programs to retrieve that information. What I am trying to do is to
analyse
a company's custom programs that are using a software database to assist
in
the conversion process. If I can see what programs are accessing
specific
files (which I can get from the DSPPGMREF) and then further define which
fields are actually being used, I can increase my productivity for the
project.

I was hoping that the information was stored somewhere that could be
accessed. Not only would recompiling be a monumental task, it would be
impossible to know what parameters were used to compile the programs for
binding, sqlrpgle, etc.

Alan,

I wonder if it would be always as simple as that. What happens if the
field is modified using embedded SQL statements? AFAIK, it wouldn't
appear as M in the XREF info..

Of course, as always, it would depend on the OP's particular needs and
requirements (maybe SQL is not a factor in his case)

Hi Eric
Maybe I'm missing something, but wont a programs XREF in the compile
listing give you where a field is defined (D) and modified (M)?

To the list,
Is there any API that could retrieve a list of field usage within a
program. I am looking for a way to determine what fields a program
is updating or writing.

Thanks...
