At risk of being accused of denying a bug, and of keeping you on internet hold for a couple days, your code indicates expected behavior. Since you were in the field when you hit control-t, you need to let the buffer know about the change. Try this: >let variable = 1 >input by name variable > on key (control-t) > let variable = variable + 1 > display variable { displays as 2} > sleep 5 NEXT FIELD variable By re-entering the field, the buffer will know about the change. In the more general case, you can: ON KEY (CONTROL-T) LET variable = variable + 1 IF INFIELD(variable) THEN NEXT FIELD variable ELSE DISPLAY BY NAME variable END IF If *this* doesn't work, then I'll blame a bug. ============================================================ Dennis J.
