RE: multiple search arguments in one scan?






Hi Dan

Have you thought about using the %XLATE BIF?

You could use the following:

                 If              TextField <> %XLate('&%*_?' : 'ABCDE' : 
TextField)
                 ...character found
                 Else
                 ...character not found
                 EndIf

It doesn't really matter what you use in the replacement string, all 
you're
doing is ensuring that the returned string is different which allows you 
to
test for something.  Depending on the length of the string you are 
checking
and the number of records being checked you may find this, whilst neater,
more of an overhead than doing individual scans.

Best regards

Nope. Gotta scan multiple passes.
If there's a lot of data records for which this is required, you might
consider using memchr() instead of %SCAN() since it will search much 
faster
than %SCAN().

Crud - severe brain fade moment...

I want to test for the existence of one of several characters in a string.

%check lets you check for the first character that is NOT found in the
"comparator".

%scan only lets you specify one search argument.

I need to test a string to see if it has any occurrences of any of the
characters &, %, *, _, or ?

There *is* an easy way to do this in RPG, is there not?

FWIW, on V5R2.
