RE: Free form question

Ok. My mistake. Compiler just doesn't like to have () if file is
declared as Sequential access.
Again, I think this is a compiler bug. If it is able to figure that out
with Key access file, it should be able to figure that out with seq
access file.

I'm on V5R3 and for some reasons my compiler is not liking it.

Yep here's the entire program:

FSvcVHdL0 IF E K DISK

d idx s like(svcnum)
/free
idx = 230;
chain idx Svcvhdl0;
dsply svcnum;
chain (idx) Svcvhdl0;
dsply svcnum;
*INLR = *ON;
return;
/end-free

Here's the output:
DSPLY 230
DSPLY 230

The record with RRN# 230 has svcnum = 458.

Charles,
Are you saying that on your F spec, myfile is coded as K on RAT column

and the compiler is not error out the "chain idx myfile;" statement?

Ok,

So I was wrong.

looks like
chain idx myfile;
chain (idx) myfile;

are both treated as chains by key field.

Sorry about the mis-information...

Charles

No it won't.

RPG always allows access to a file via RRN. Even if it defined as
keyed.

Depending on the F spec, compiler will error out one of those two
chain statements in your example.

I really not sure why compiler need developer to tell him
if the chain
is by key or by RRN. It should be able to know that from
the F spec,
just the fix format.
