Jesus,

Thank you, I cannot guarantee that the data will always be in the same 
format, however I know that the length of the string is always the same. 
Can I pase the string one character at a time, and apply a set of rules 
to determine what data to use and what data to discard?

For example I know that I want to use only the numerical data and not 
the alphabetic data. The simplest, though not elegant way I can think of 
is to go one character at a time and determine if that character is a 
number or a letter.

Bob
