Hi msabhi,

I think lancesunny is talking about position of the string..

so NR can be used like this...

i know this is not the efficient way..
try..Smilie
Code:
while read line
do
echo "$line" | sed -e 's/.\{1\}/&\n/g' | awk '{if((NR>=351 && NR<=357) || (NR>=24 && NR <=43)){gsub("-","0");} else if(NR>=381 && NR<=382){gsub("  ","04");}}1' | paste -sd ""
done<file

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
