Alternate solutions similar to your original method...
The BEGIN section is executed prior to the main body of code. Here we load the shell variable into a local variable for use in the print statement.
The "quotes" protect the variable name from being part of the sub-shell and passes the parent shell information down
The reason why your original code does not work is that awk runs in a sub-shell to the parent with no variables being passed down (don't remember why the BEGIN statement works though... I'll have to research that). Someone please correct me if I'm wrong, but that's sorta the way I remember it (geez I'm getting old... memory is fading!)
