Re: Passing Datastructure Array

This is a proof of concept I was working on. No worries, I wouldn't put
it into production usage. I just needed to get a down and dirty example
working, but your warning is well heeded as it can sometimes be an easily
forgotten tidbit.

Re: Passing Datastructure Array






Note,

You should not define variables with a name starting with SQL (ie you
sqlDS).

IBM reserves SQLxxx names for it's own use.

It might work today, but tomorrow is another story.

And what seems like it should work, doesn't. So I turn to you RPGLE

The Problem... I'm trying to pass a datastructure array to a

subprocedure

to do a "%lookup" since %lookup doesn't support qualified names. The
problem is that I'm getting a compile error that says "RNF0528 Index is
not allowed for name that is not an array; index is ignored." It is
basically saying that the array in my PI isn't an array...

The Code...
D FindFSOds...
D PR 2s 0
D EntryDS LikeDS(sqlDS)
D ShopOrder...
D 6s 0
D
D sqlDS ds qualified Dim(20)
D Shop_Order...
D 6s 0
D Parent_SO...
D 6s 0

P FindFSOds...

D FindFSOds...
D PI 2s 0
D EntryDS LikeDS(sqlDS)
D ShopOrder...
D 6s 0

D
D ArraySize...
D c Const(20)
D rtrnIdx...
D s 2s 0
D x...
D s 2s 0
/free
rtrnIdx = 0;
for x = 1 to ArraySize;
if EntryDS(x).Shop_Order = ShopOrder;
rtrnIdx = x;
leave;
endif;
endfor;

return rtrnIdx;
/end-free
P FindFSOds...
P e
******************************************************************end of
code

The compiler error points to the "if" statement and says that the

EntryDS

can' have (x) because its not an array. Doesn't the like DS mean that

it

is? And that it will automatically be qualified?

I'm confused. What am I missing?
