It would help if you gave some sample outupt. It helps to break up the awk from a single line and use multi-lines to show the
inner-clauses of if, for example...pretend this was just awk
script the code would look like
Code:
{
if (substr($0,37,1)==1 && NR == 3)
    print "YES" 
 else if (substr ($0,37,1)==0 && NR == 3)  
      print "NO"
}

you also didn't post why "this doesn't work". Provide some sample input and show the results of what you say.

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
