Quoting "The AWK Programming Language",

	"The cleanest way to do case conversion in awk is with an array that
maps each letter...it's better to use...tr"

I often use tr for this very reason. For example:

	echo "HeLlO, wOrLd!" | tr [:upper:] [:lower]

This gives you:

	hello, world!

To use tr from awk:

#!/bin/awk -f
   {
   "echo "$0" | tr [:upper:] [:lower:]" | getline
   print
}

To skip the first character:

#!/bin/awk -f
   {
   start_of_line=$0
   rest_of_line=$0
   start_of_line=substr($0,1,1)
   rest_of_line=substr($0,2)
   "echo " rest_of_line " | tr [:upper:] [:lower:]" | getline rest_of_line
   print start_of_line rest_of_line
}

	Sincerely,
		Tom
