[plug] script debugging

[Jon Miller]

Is there a way to turn on a debugger while running a script.  I'm looking
for something that can go line by line and when an error arises it stops. 
The problem is I have a script that gives me the same error at the same spot
and I cannot see what the problem is. 
On the same note if there are functions developed in the script and I want
to call them at the end of the script do I need to put a ";" after each
function or just the last function.  From what I understand ";" mean end of
command.  If this is true then it should only be put at the end of the last
function.  If this being the case do I still need to put a exit 0 on the
very last line.

Thanks
