Hi all,
Does RPG implicitly cast a varchar return value (from a procedure) to char when the receiver variable is char?
Sample random code (2 lines):
dcl-s CharacterVariable char(50) inz(' '); //character date type
CharacterVariable = EmailAddress ( 'Bob Saget' ); //EmailAddress has return value defined as varchar(50).
Although this appears to work for some of my teammates I was told by Bruce Vining (remember Bruce??) that if IBM does not explicitly document a behavior then one should never assume it to be true "just because it works for you." (paraphrasing Bruce).
I believe his exact words were, "Bad things can happen." :)
I was thinking of instructing my team to make this practice verboten, but I thought I'd ask the list first.
Unless I'm blind I could find no text in the RPG Reference to address this, much less come close to implying it.
Regards,
