Re: %scan not working as I'd expect...

ALL,
Thank you for your replies. You are all correct. I need to %trim
Criteria. I seem to forget about those embedded blanks.


Thanks

Bryce,

Criteria is fixed len, thus you're not looking for 'HOSPITAL'
you're looking for 'HOSPITAL '

Bit of a difference. :)

Consider this parameter definition instead...

D Criteria...
D 30a CONST VARYING
OPTIONS(*TRIM)

HTH,

Charles

I'm trying to use the %scan bif and it doesn't seem to be working. I

must

really misunderstand how it works or something....

short example....

D Criteria...
D 30a //parameter for my
procedure.

D name1...
D s 30a
D pos...
D s 10i 0
/free
....some sql code to populate name1.

pos = %scan(Criteria : name1);

....some more code later on
/free


I'm using a SEP to debug this. When the %scan is performed the value of
pos is being returned as 0. Criteria = HOSPITAL, name1 = '**MY EXAMPLE
HOSPITAL'

Why is pos = 0? HOSPITAL is CLEARLY in there... shouldn't it return

the

position on the H? Which in the real data for my first record I would
expect to be position 19. In this example I would expect it to return
position 14.

Am I missing something?
