Doing one thing multiple times

Hi,

I wrote a awk line here:

awk 'BEGIN {OFS="\t"} {print $0, int(rand()*($2-$1 + 1) + $1) }' filename

Basically what it does is that it takes the start (column 1) and stop (column 2) and generates a random # in between start and stop.

I want to take this a step further and have it generate 100 random numbers at once. How would i do that? is it called looping?

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).

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
