Aha!  This helped tremendously.  It actually turns out that gp was looking for 
me to put ';' after each of the 'for' statements as well.  It now works 
perfectly.  Thanks for the help.

This helped as well.

Its strange.  I have a variable defined that contains a string pointing to the 
file in question, lets call it str_file.  When I type '\r str_file', its acting 
like str_file "is" the file I want to open and says "error opening input file: 
str_file" with a little arrow pointing to the 's' in str_file.  However, when I 
call read(str_file) it works just fine.  Am I calling '\r' incorrectly?
