Hi David,
what do you think about using a field reference file and define all your
fields (parameter fields, work fields, file fields ... etc) with like based
on this reference?
That's the way we work. When changing a reference field everything must be
recompiled but we do not care about anything else.
The field reference file is included as external based data structure (we
are not yet on release 6.1 so we cannot use the keyword TEMPLATE), in every
RPG source member we use. All Fields are refeneced:
Example
D/If not defined (FldRef)
D/Define FldRef
D FldRef E DS ExtName('MYFLDREF') qualified
D Based(DummyPtr)
D/EndIf
D MyProc PR
D ParAAA Like(FldRef.AAA) Const
D POutCCC Like(FldRef.CCC)
D ParBBB Like(FldRef.BBB) Const
D Options(*NoPass)
D MyVarAAA S Like(FldRef.AAA)
D MyDS DS Qualified
D XXX Like(FldRef.XXX)
D YYY Like(FldRef.YYY)
Mit freundlichen Grüßen / Best regards
Birgitta Hauser

Pah! The compiler can't protect you from stupidity. The
problem was caused entirely by you trying to stuff 9 pounds
in a 7 pound bag and not expecting it to overflow i.e., not
paying attention to what you were doing. Sure, without CONST
or VALUE the compiler would have caught the mismatch but
consider the reverse situation where you might want to pass a
smaller value or a different data type or a literal;
I don't need to consider the reverse situation here. Its just a simple case
as with most of our procedure calls of wanting to pass a variable from one
procedure to another and wanting the compiler to check that for me. If
you're saying that I should have checke the attributs of each of the 20 or
so parameters myself then what's the point of having a compiler that is
capable of checking?
