Adding array element in KSH
All,

I would like to add the first 10 elements of an array. Here is how I am doing it now (only included first few add ops):

#!/usr/bin/ksh

###Grab the array values out of a file###
TOTAL=`awk '/time/' /tmp/file.out | awk '{print $4}'`

set -A times $TOTAL
SUM=$((${times[0]} + times[1] + times[2]))

I would like an easier method of adding the elements...

Thanks!

Mike
