Operating Precautions
Appendix A
In the above example, the subroutine will be branched from the 1,000th line to the 100th line using the ON
ERROR GOTO command if an error occurs.
In this case, exit from the subroutine by changing the 110th line from RESUME 20 (to resume from the 20th
line after error processing) to RESUME NEXT (to resume from the line following the line that caused an error.)
ASCII Unit Operation when Program Memory is Damaged
When program memory is damaged a PROGRAM MEMORY ERROR or a Special Unit error on the PC side
will occur and CPU Unit operation will be held. The PC can be restarted by using the default switch on the back
panel of the ASCII Unit. In this situation, the program memory will be forcibly initialized, so always be sure to
use ROMSAVE to save programs to flash ROM memory after inputting them. Refer to
Reading the BASIC Pro-
gram from Flash ROM in 7-1 Programming Procedure , for details on how to load the saved program to flash
ROM.
Be careful when overwriting data in the user memory area using the POKE command, as damage to the pro-
gram memory may result. When damage to the program memory is caused by the use of the POKE command,
a memory error may not occur immediately.
