RE: Using eval on debug command line -- RPG400-L

Thanks Vern, especially for the reminder to use help:
because I neglected to do that, I was throwing code instead of
learning to use the tools provided...rtfm

You might like to know that you can use a substring in the debug session, too - hit F1 on the command line to get details under the EVAL command - it's kind of clumsy but sometimes useful.

You can also view variables in hex, using :x instead of :c - and the length can be specified, as you show below.

Thanks Bill,
I was trying to copy contents of a long field to a DS, using:
EVAL myDS = longfield
- and that failed.

My idea was to be able to view contents of an approx 5000 char field
but I was hitting a limit of 1024 characters, so I had made a
5K DS with 1K fields and was using EVAL to copy to my DS

Scott K. pointed out I can overcome the 1K limit with "EVAL longvar :C 5000" (or similar)
which was news to me and works great and far better than my clumsy hack.

I'm not sure what you're trying to do with the EVAL, but If you are trying to see the value of the DS, just use an EVAL = DataStructureNAME, if you're trying to change the DS, use an EVAL = DataStructureSubfield.
Hope this helps

Thanks Barbara. I'm too much an rpg hack, but I can change, someday, maybe.

Why do I get an "Assignment type error occurred."
when I code an eval on the debug command line that attempts to copy
a 5k byte field into a data structure?

RPG considers a data structure to be also a character field, but the debugger thinks a data structure is just a data structure.
