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

[Charles Wilt <charles.wilt@xxxxxxxxx>]

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
