Stepping through Your Program
When SoftBench Debugger loads a program, it begins executing the
program and pauses at the first line with a breakpoint. You can then use
SoftBench Debugger to execute your program one or more statements at
a time.
In the default configuration, SoftBench Debugger displays the following
buttons above the Debugger Output Area:
Step Execute one statement, then stop. This is called single
step execution.
Step Over Execute a statement, treating any procedure call as a
single statement. SoftBench Debugger calls the
procedure, but control does not return to the debugger
until the procedure returns. When the PC is just before
a procedure call, this has the effect of "stepping over"
the call.
Continue Out Finish executing the current procedure. Run without
stopping until the current procedure completes and
returns to its caller (or until SoftBench Debugger
encounters another breakpoint or similar event), then
stop. Use this when you accidentally step into a
procedure that you do not want to step through, or
when you interrupt your program in the middle of
non-debuggable code. Each Continue Out causes your
program to "pop out" one procedure level.
When you select one of these buttons, the PC arrow moves to the next
statement to be executed.
SoftBench Debugger steps over undebuggable routines, such as system
library routines and routines that were not compiled with the debug
option, even when using Step.
To pause at a specific point in your program, see “Setting and Using
Breakpoints” on page 189.
