A couple of things that might be causing your problems...

First, you say that you want to print the desired fields when field 2 is between 1 and 35 (inclusive) yet your if statement prints only when less than or equal to 31. There's a typo in your code, or your problem statement.

Secondly, some of your values in column 2 are not numeric. I have seen some versions of awk do funny things with an expression like

Code:
if( $2 <= 35 ))

when the value of $2 is something like "foo" rather than a number. To prevent this from happening, I generally write the expression like this:

Code:
if( $2+0 <= 35 )

This forces awk to convert the value of $2 into a floating point before the comparison is made. If the value of $2 is not numeric, it will convert to 0 (zero), and something like 123abc will convert to 123.

Neither of these may be your problem, but without an example of what you are getting as output and what you are expecting it is difficult to guess.

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

       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)
		 ...
       }
