Short and sweet response there, David. While correct, I believe it can
be expanded just a tad. :-)
If you want your code to stop running, use the 'stop' procedure. When
your code encounters a stop, it will immediately stop executing and
you'll be left in interactive mode. You can put the stop within a catch
block of the subroutine you're working on and whenever an error is
encountered the program will stop and you'll be able to look at
variables, run other commands, etc. Just make sure to remove the stop
before distributing your program.
If you want to redo calculations of the subroutine only, you'll need to
break the subroutine out into it's own file. I don't know if anyone
else does this, but I will usually first write subroutines in their own
files just so I can easily test. Once tested somewhat, I'll move the
subroutine o the proper location within the file where the subroutine
actually belongs.
