Re: Subprocedure use of a Global file

Thank you Scott and Charles.

I agree that my assumption was wrong, I was just "thinking out loud". I
have never had this happen before.


Here is the source:

The single call:

prc_items(key01 : bbnumber);


PI

dcl-pi prc_items;
@_key01 like(bbkey01) const; [packed 9]
@_billback# like(bbnumber) const; [char 15]
end-pi prc_items;


The code in the subprocedure:

chain (@_key01) bbhdrp;

if %found(bbhdrp);
s4number = %trim(bbnumber);

if s4number = *blanks;
s4number = @_billback#;
endif;

After the Chain, bbnumber is blank, which it should be. After the chain
@_billback# is blank too, but not before the chain. I did a small test
where I saved the @_billback# before the Chain, and that variable did not
change, so I must be overwriting something, but I don't see what it is.
This is the only occurrence of @_billback# in the whole program. I just
did a small test where I made @_billback char(15) to satisfy my curiosity
but @_billback# was still blank after the chain.
