That's really helpful, but what I'm trying to figure out how to do is 
grab data from a plain text file.  Columns are delimited by spaces, but 
the third column (the last) also contains spaces.  So I'm really 
searching for a char, an integer, and then a string delimited by a space.

How would I go about doing this without regex?  I know how to use regex, 
in a general sense, but I don't need it for something this simple.

Thanks for your time Jarrett.
