A program can be executed in different ways from
the Debug Environment. Single line execution of the
current line can be initiated by clicking on the
Step
command button. The
>>>>>>
symbol preceding
the line number indicates the line to be executed.
The program can be executed to the next breakpoint
encountered or end of program by clicking on the
Run
command button. Clicking on the
Halt
com-
mand button will stop a Running program. A pro-
gram that is running can also be placed in the Single
line execution mode by clicking on the

command button.
Note: The program status indicator shows the
status of program execution. The only time this
status will indicate Stopped is when the program
is halted or has executed an end statement in the
program. The indicator is green for running and
red for stopped.
12.2.2 - Breakpoint Setting/Clearing
Up to five breakpoints can be set in debug mode. To
change the breakpoint setting of a line, click on the
desired line and then click on the

points

breakpoint, a

breakpoint line numbers can be listed or cleared by
clicking on the
List breakpoints
command button
and than the appropriate command button.
