7-8-2 Breakpoint Function (BRKPT)
232
The debugging function allows you to stop the program at a specified line by
various methods so that the contents of variables can be monitored. It is also
possible to determine the position of the current line number.
Note The breakpoint function can be used to set a breakpoint in an interrupt sub-
routine, but it is not possible to continue executing the interrupt subroutine
after the breakpoint.
By command input Break at multiple
from the terminal lines (255 settings
max.)
Break after a
single line or
specified number
of lines
Execute up to the
specified line
By internal Break at the
program command specified line
By command input from
the terminal
TRON command
TRON[M] command to TRACE command
input
Each of the following debugging functions are described below.
• Break point function
• STEP function
• Variable monitor function
• Trace function
When a breakpoint is set at a specified line using the BRKPT command, the
program will stop at that point. Once it has stopped, a message indicating a
break in execution and the current line number will be displayed at the termi-
nal. The ASCII Unit will switch to Command Mode. Up to 255 breakpoints can
be set. To restart the program from the breakpoint, enter the CONT command
from the terminal.
