Thanks for all the great replies guys. I enjoyed playing about with your script Don!
You can turn this into a little 'find the hidden character' type game to. For example, find the hidden $ in a diamond full of S's. Or one of my favorites, find the hidden ";" amongst the ":"'s! (this really gets tricky at larger sizes!) Expanding on my initial code (again a much more elegant solution exists!):
I have to print the number of stars that increases on each line from the minimum number until it reaches the maximum number, and then decreases until it goes back to the minimum number. After printing out the lines of stars, it should also print the total number of stars printed.

IGAWK(1) Utility Commands IGAWK(1)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
