Hi Brett,

Thanks for the tip, I had some flex notes to make use of some day,
but my challenges are far simpler than that!

FLEX Tutorial
http://alumni.cs.ucr.edu/~lgao/teaching/flex.html
First, FLEX reads a specification of a scanner either from an input
file *.lex, or from standard input, and it generates as output a C
source file lex.yy.c. Then, lex.yy.c is compiled and linked with the
"-lfl" library to produce an executable a.out. Finally, a.out analyzes
its input stream and transforms it into a sequence of tokens.

your comment helps me put it in  to context anyway.  :)

-George
