Couple things:

About the subroutine declaration, and the declaration
of the parameters I want to pass to it, I do it
because that's how I understood the book to tell me. 
Besides, I'm comfortable with it that way as it helps
me organize my thoughts.

About declaring variables in while loops and if
constructs.  I don't do that because it's messy and
disorganized for me.  I prefer to declare all the
variables I will use in a subroutine at the top of the
subroutine, before I write any assignments or process
any code.  It's just a style I prefer.

About the die statement.  Point taken.  It wasn't a
priority for me at the time.  Same thing with naming
the array variable @stuff.  Yes, I know that it is a
poor name for a variable.  I was testing and that's
the first word that came to my head.  If it worked,
it's name would have been changed, as it didn't, well,
it'll just be deleted.

the name of the subroutine?  Point taken.  I didn't
notice it, as this was code that I've adapted from a
subroutine i had written earlier that did parse the
line within it.  It was just easier to keep the name
the same.  But that's a good point.

What I want to return is the count of the number of
fouls, nothing more.  However, I am a bit lost as to
how to count them.  Can someone point me in the right
direction to figure out how to count that?

To prevent someone from thinking my intentions are to
be rude, they aren't.  I appreciate the help I get on
this list. -stu
