OT-Passing variables to a awk/sed script

Hello List,
 

This must be piece of cake for the UNIX gurus.
 

Trying to pass parameters to a  simple awk script. Getting stuck.
First q., can we do that.
If yes I need to solve the foll. problem,
 

In a huge text file locate for  "abc/xyz" and replace it with a supplied parameter value. This paramter must of course, be able to take on any value during the run of the program.
 Any help or tips on that would be highy
appreciated.
 

Thanks
