[ale] awk masters...

[jojerose at mindspring.com]

quick question
I'm writing a script to search a file for specific codes, If the codes are found, I want to extract the record from the file.  goes something like this...

for i in `cat codes.dat`
do
     awk '{if(substr($1,7,2) == '$i') print $1}' recs.dat > newfile.dat
     ....
     ....
done

it's the $i that i can't get to work.  awk thinks it is one of 'its' variables.  How can I get awk to recognize it as a shell variable?

Thanks for the help
