Luís, make sure bi.ref value is really what you're expecting (and the cursor is not EOF(), for instance).

CREATE CURSOR bi (ref C(20))

INSERT INTO bi (ref) VALUES ('0.600/1182')
GO TOP

IF LIKE('0.600/*', bi.ref)
	MESSAGEBOX("True: " + bi.ref)
ELSE
	MESSAGEBOX("False: " + bi.ref)
ENDIF

SKIP

IF LIKE('0.600/*', bi.ref)
	MESSAGEBOX("True: " + bi.ref)
ELSE
	MESSAGEBOX("False: " + bi.ref)
ENDIF
