You do this: FUNCTION construct_rtn() DEFINE value CHAR(70) # Size needs to be as long as the longest field to # be popped up on. CONSTRUCT global_buffer ON tablename.* FROM screen_record.* ON KEY(F2) IF infield(field_1) THEN CALL popup_rtn() RETURNING value # This will display and link value to the field buffer DISPLAY value to field_1 END IF END CONSTRUCT -- Robert Minter Data Systems Support Programmer, Software Development Orange, CA internet: rob@dssmktg.com Tel: 714.771.0454 bangpath: uunet.uu.net!dssmktg!rob Fax: 714.771.3028
