lex and yacc help desired

[Allen Wade]

Hello,

I am fairly new to Lex and Yacc and I am tring to develop a 
language definition for a small report processer. I have the book 
Introduction to Complier Construction by Scheiner and Friedman,
But I feel a little lost as how to start. My input lines will
generally look like this:

|MEDINA|ANTOINIO|01/14/62|M|(312)778-2540|60629|GARFIELD|LAREN|GP|DC101A|

I am able to figure out the regular expressions for Lex, but I am confused
about how Lex and Yacc work together.

Any help will be most appreciated.
