i tried like this

while read alpha
do
awk 'substr($0,3,7)<"$alpha"||substr($0,81,7)<"$alpha"'<ecscrfinal >> mkoff.$alpha
awk 'substr($0,3,7)<"$alpha"||substr($0,81,7)<"$alpha"' <ecsdrfinal >> mkoff.$alpha
done < /home/ftp/ecs/usercode

which yielded no results

then like this, $alph without quotes;

while read alpha
do
awk 'substr($0,3,7)<$alpha||substr($0,81,7)<$alpha'<ecscrfinal >> mkoff.$alpha
awk 'substr($0,3,7)<$alpha||substr($0,81,7)<$alpha' <ecsdrfinal >> mkoff.$alpha
done < /home/ftp/ecs/usercode

In this case the entire file is copied to all the userwise split files

What I am doing wrong..... Cant I do substitution inside awk...??

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
