what ascii keycode stops program execution in vb6

[hamptondude]

I want to stop a program running in VB6 to check code. What is the ascii keycode to do this??
(CTRL-BREAK DOES NOT WORK)

Advance programming one line at a time while debugging (VB6). What ascii keycode does this??

The simple answers are;
Put the cursor on the line where you want to stop the code and press F9. The code will then be highlighted in red and execution will stop at this line. From there, F8 will advance execution one line at a time.

I presume there's more to the question than just this.
