Caution
(1) To force an end to the repetitious execution of the FOR to NEXT loop during the execution of the
loop, insert a BREAK command.
(2) Use the EGP, EGF commands to conduct index qualification for the FOR to NEXT contact.
(3) Be sure not to execute the END (FEND) command after the execution of the FOR command but
before of the NEXT command.
(4) Always execute the FOR command prior to the NEXT command.
(5) Be sure not to insert the STOP command within the FOR to NEXT loop.
