Is there a way of find the POSITION of a string of hex characters within a character string, WITHOUT using BLOB data.

The specific example is that we are looking for the POSITION of the carriage-return line-feed within a string of character data.

DECLARE a integer;
SET a = POSITION ( X'OAOD' IN InputRoot.XML.textBox)

I know this doesn't work (illegal operands), however it should give you an idea of what I'm trying to accomplish.

thanks.

Actually, I've found a work around for this.
DECLARE x INTEGER;
DECLARE c CHARACTER;

/* do not change the assignment of "c", it is meant to look that way */
SET c='
';

SET x=POSITION( c IN OutputRoot.XML.textBox);

You could let WMQI 2.1 do the hex to char conversion for you as follows:

SET a = POSITION ( cast(X'OAOD' as CHAR CCSID 850) IN InputRoot.XML.textBox);

Don't forget CCSID parameter!
