It's only invoking the backtics once, so no surprise there. In this case, the text you want is not static, so the workaround doesn't work.

If your awk script is no more complex than this, why do you need awk in the first place? Also note that newer versions of awk have a built-in rand() function. Or if you don't have that, but are on a platform which offers /dev/random maybe you can use that from within awk instead.

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)
		 ...
       }
       EOF

       igawk -f test.awk
