By using the above commands, the program is debugged. As an example, the
following sample program is debugged.
10 PARACT 0
20 A = 3 : B = 4
30 FOR I = 1 TO 3
40 A = A + B
50 PRINT A
60 NEXT I
70 END
80 END PARACT
Execution can also be stopped from the keyboard by inputting CTRL-X or
CTRL-C. When CTRL-X is input, all execution, including I/O processing, will be
aborted immediately and "Quit in ..." will be displayed. STEP and CONT cannot be
used after aborting execution with CTRL-X. When CTRL-C is input, execution is
stopped as soon as the current instruction has been executed. If "Break in ..." is
displayed, STEP and CONT can be used. If "Quit in ..." is displayed, STEP and
CONT cannot be used.
Note Data received while program execution is stopped may not be retrievable after
CONT is executed. To avoid this problem, make sure that data has been received
and jump to the address defined with ON PC before setting the BREAK point.

6. If an error is found on a line of the program while the program is executed,
the execution is stopped at that point, and the line number and an error mes-
sage identifying the nature of the error are displayed. To correct the error,
display the line by using the EDIT command, input the correct command,
and press the carriage return. Then input again and execute the program by
the RUN command. If another error message is displayed, correct the pro-
