I don't think you can do 'case >= 4'.
Also, ext=mb sets ext to blank unless mb happens to be set to something. I think you meant ext="mb"
Try: ext="kb" ; if(value >= 4) ext="mb";
Also, print "BOLD$1RESET" will print the literal words BOLD and RESET and the literal text $1. awk really is a different language than shell, it doesn't substitute inside quotes -- in fact it doesn't substitute, at all, ever. If you want the variables, do print BOLD $1 RESET
Lastly, and most importantly, you forgot to give awk a filename.

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
