Hello all...

I'd like to create a variable from an array element from two arrays. In my search for answers I found this code for bash that joins two arrays and then started to work with it. I had got to work once and then foolishly without saving the code, I started to edit it for ksh and subsequently broke it. Now I can't get it to work again. Any suggestions?

BASH CODE >>>

#!/bin/bash

NAME=([0]="John" [1]="Mary" [2]="Fred")
SURNAME=([0]="Doe" [1]="Poppins" [2]="Flintstone")

# this gets args from command line and add them to the arrays.
# it's NOT the Right Thing, but can give you a brief idea of what to do
# You may add options, like -name "list" -surname "list" to parse the
# correct elements and insert them in the appropriated array.
for i in $@
do
# this ugly stuff inside brackets counts the number of elements
# so every new element added increases array counter.
NAME[${#NAME[@]}]=$i
SURNAME[${#SURNAME[@]}]=$i
done

# starts loop at element 0 and stops at last.
for ((i=0; i < ${#NAME[@]}; i++))
do
# echo element number, name and surname.
echo "Howdy #$i: ${NAME[$i]} ${SURNAME[$i]}"
done

<<<

What I thought I had come up with was:

MY VERSION OF THE BASH CODE >>>

NAME=("John" "Mary" "Fred")
SURNAME=("Doe" "Poppins" "Flintstone")

for i in $@
do

NAME[${#NAME[@]}]=$i
SURNAME[${#SURNAME[@]}]=$i
done

for ((i=0; i < ${#NAME[@]}; i++))
do

echo "Howdy #$i: ${NAME[$i]} ${SURNAME[$i]}"
NAME[$i]=${SURNAME[$i]}
done
echo "$John"
echo "$Mary"
echo "$Fred"
