RE: Global variable search -- RPG400-L

As far as I'm aware, you can't have a procedure w/in a procedure (I just tried), so an ending P-spec will always be associated with the beginning P-spec you have just encountered. No need to match up the names.

I think this is going past the original topic, but if you wanted to create diagram all of a module's procedures, you could do something like this:

1. Read through code.
2. PR encountered w/no P-spec encountered. Save the name.
3. Read for PI. Create your diagram based off of the PI and its parameters, using the procedure name from #2.
4. Continue reading, this time looking for a P spec. First P-spec encountered will be your Beginning P-spec. (You don't even need to look for the 'B' - especially since it may not be on the first line of the P-spec. Process the PI that comes afterward. Use the name from the P-spec (instead of the PI).
5. Read for the ending P-spec ('E').
6. Rinse & repeat starting at #4.

Not a well thought out flow, but it's what I got off the top of my head.

Kurt,

What if the ending P-spec doesn't have a name either?

Well, look for a P-spec with a B notation with the same name as the PR
(remember the potential for ellipses). The PI after the P-spec does not
have to have a name on it.

e.g.
P isInternational...
P B
D PI n

Hi Vern,

First, a prototyped main is going to have PR in a certain position of D
specs. So you have a test for a prototype. Then the name will be the
same as the program - it will be 10 characters and somewhere near the
beginning of the D spec with PR in the right place.

The name doesn't have to be the same as the program. It also doesn't
have to be the same as the name of the module. You can make the name of
the prototype anything you want.

If you're trying to find the parameter list for a main procedure, you
just have to keep track of whether you've already seen a P-spec. If you
are outside of the P-specs (i.e. not between the Begin and End P-spec),
and you encounter a PI, it's the entry parameters for the main
procedure. Nothing to do with the name.

If you need to know info from the PR, then look for a PR that has the
same name as the PI.
