I came across this code

REPLACE ALL RefPartNo WITH IIF('@' $ RefPartNo, SUBSTR(RefPartNo,1,AT('@',RefPartNo)-1), RefPartNo)  IN 'zUniqs'
REPLACE ALL RefPartNo WITH IIF('+' $ RefPartNo, SUBSTR(RefPartNo,1,AT('+',RefPartNo)-1), RefPartNo)  IN 'zUniqs'

and am wondering if

REPLACE ALL RefPartNo WITH GETWORDNUM(RefPartNo,'@+') IN 'zUniqs'

really is the equivalent expression I think it is. I wasn't able to find a difference, but I may not have tested all conditions and am looking for reassurance.

Thanks.......Rich
