Running Your Programs
6-11 Loading, Displaying, and Running Code
?/eval
-
You can directly modify the PC’s contents with one of these commands:
?PC =
new value
or
eval pc =
new value
After halting execution, you can continue from the current PC by reissuing any
of the run or single-step commands.
Running code
The debugger supports several run commands.
run The RUN command is the basic command for running an entire program. The
format for this command is:
run [ expression]
The command’s behavior depends on the type of parameter you supply:
-
If you don’t supply an
expression, the program executes until it encounters
a breakpoint or until you press
ESC
or the left mouse button.
-
If you supply a logical or relational expression, this becomes a conditional
run (see page 6-14).
-
If you supply any other type of expression, the debugger treats the expres-
sion as a count parameter. The debugger executes count instructions,
halts, then updates the display.
go Use the GO command to execute code up to a specific point in your program.
The format for this command is:
go [
address]
If you don’t supply an address parameter, GO acts like a RUN command with-
out an expression parameter.
ret The RETURN (RET) command executes the code in the current C function
and halts when execution returns to its caller. The format for this command is:
return
or
ret
Breakpoints do not affect this command, but you can halt execution by press-
ing
ESC
or the left mouse button.
F5
Pressing this key runs code from the current PC. This is similar to entering a
RUN command without an
expression parameter.
