Re: How do I find the length of a field that is externally defined?

I know how to find the length manually.   It is shown in the compile of the
RPG program.  What I actually do is just make the field overly long, say 600
for example.

However that's not quite the problem I wish to solve.  I want the DDS to not
need to be corrected if the data file has a field changed or added.  You
know, the same reasons that we use REFFLD and REF, right?  It isn't a
serious issue but it is the only glitch I haven't been able to  get around.

Neat technique, Booth!  I don't know of a way to tell DDS that you want a
single character field sized the same as an entire external PF/LF record.  I
guess I'd just DSPFD the PF/LF and find the record length if it were only a
handful.  If I were doing a bunch of these things, I'd write some sort of
macro and then run the source through a pre-processor (that I would also
write.)  Of course this predicates sending your pre-processor to every
customer you do work for...
