When debugging, how to jump over steps of a PAUSE ?

John Kauffman

My SX/B program has some commands of Pause 200. When I run Debug it takes hundreds (?) of steps to get through the pauses and on to the commands of interest.

What is the best practice to avoid all of that stepping through PAuse? So far I have tried the following techniques:
·
-········ REM out the pauses prior to running a Debug.
-········ Make all the pause length arguments a single variable so I can set that to zero (changes all the pauses with one change)
-········ Change the walk speed during debugging to ‘run’ past the pause steps and ‘plod’ through the interesting steps (this ends up like a video game).
·
Are there other techniques?
·
Ideally, I’d like a directive or command like: DEBUG IGNORE PAUSE

You could define a constant used to skip those sections when you want to debug.· You'd have to change the constant for normal operation, but this is a simple step:

Yes······ ·CON··· 1
No······ · CON··· 0
DebugOn··· CON··· Yes

...

· IF DebugOn·= No·THEN
··· PAUSE 200
· ENDIF

John,
You are only allowed one break point, BUT if you put the breakpoint in a subroutine you can have as many as you want.
And since the debugger actually stops on the instruction AFTER the breakpoint, you are stopped right at the instruction after the call to the BreakPoint subroutine.

Here is an example program. Start the debugger and hit RUN, it will stop at "a = 5", now you can step until you get into the PAUSE command, then just hit RUN again, the debugger will stop at "a = 10" and so on. (I hope that made sense...).

DEVICE SX28, OSCXT1, TURBO, STACKX, OPTIONX
FREQ 4_000_000
 
a VAR Byte
 
BreakPoint SUB
 
PROGRAM Start
 
Start:
  BreakPoint
  a = 5
  PAUSE 200
  BreakPoint
  a = 10
  PAUSE 200
  BreakPoint
  a = 20
  PAUSE 200
  GOTO Start
 
BreakPoint:
  BREAK
  RETURN

Jon: thanks for IF THEN option
Bean: that makes perfect sense.

Thanks to both.

Hey Bean, I like the idea of putting the BreakPoint in a subroutine. It never occured to me
