Hello,
Hmm, one of the first problems that comes to mind with the %char bif
is zero. What if you wanted to test for 0 in your list? I think
%char(0) returns a zero length string...
Huh? Why would %CHAR(0) return a zero length string? It'd return a
string one character long containing '0'.
Do you need to accommodate negative values? If so, I'd suggest
%editc(chk1 : 'J') and test for values padded with space (positive)
or a "-".
%EDITC doesn't trim blanks, so you'd have to add an additional %TRIM()
to your statement. Yuck. Again, what's wrong with %char() here?
if %scan(%char(chk1): '-1|-7|-8|-9') > 0;
I don't see why that wouldn't work?
For the record: I don't like any of these %SCAN kludges. I'd much
rather see the normal if/or/and syntax that already exists in RPG. That
will perform better _and_ it's easier to read/maintain. But, if you
must use an ugly kludge, I'd rather see %CHAR() than %TRIM(%EDITC())
