RE: multiple search arguments in one scan?

[rob@xxxxxxxxx]

Based on a request he made to midrange-l I suspect that he's only scanning 
a screen input field to see if he should use LIKE or equal on a dynamic 
sql statement.  (That and the list of characters he's searching for.)  So 
I think it's not a lot of records.

RE: multiple search arguments in one scan?






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.
