4 Interaction between Programs and Forms
TAB and RETURN
When the program is waiting for input, either TAB or RETURN can be used. The TAB key moves the cursor from one input field to the next. It does not take the program out of the waiting state. The RETURN key does not tab through the fields. It returns the program to the execution state. If the next statement is an input statement, the cursor is displayed in the next tab field and it appears that RETURN has tabbed to the next input field.
