I think I'd be worried about the 30 being mistaken for the length in
this case. (Not by the compiler, of course, but by the programmer
reading the code.)

Something like VARYING4 doesn't have that problem.... Just food for

Thanks for your thoughts on this, Scott. We have thought about
VARYING4, but we would want to allow the explicit VARYING2 as well, and
we think that it's more clear that VARYING and VARYING(2) are equivalent
than that VARYING and VARYING2 are equivalent. The concept of a default
parameter is common in RPG, but VARYING2 looks like it means something
different from VARYING.
Ultimately, people have to know what the syntax means anyway, but I
agree that it's ideal if someone reading the code can guess right about
what it means.
