My problem was with "sh" not "bash"! I was initiating the script
incorrectly.
Pierre Gaston pointed out my mistake and it works fine now.
Sorry for the alarm and my stupidity!
Best,
Jim

Bash Version: 3.2
Patch Level: 25
Release Status: release

Description:
        Declare: not found error
        read: -a  illegal option
I have two machines running Bash ver. 3.2 and one running 3.1.  I get the
above errors always on the 3.2 boxes but not the 3.1 box.

statements that cause the problem are:
declare -a arrayname
read -a arrayname

Repeat-By:
        here is a test script that repeats the errors:
____________________________________________________________________________
____________________________________
#!/bin/bash

declare -a colors
# Permits declaring an array without specifying size.

echo "Enter your favorite colors (separated from each other by a space)."

read -a colors
# Special option to 'read' command,
# allowing it to assign elements in an array.

echo

  address@hidden # Special syntax to extract number of elements
in array.
# element_count=${#colors[*]} works also.
index=0

# List all the elements in the array.
while [ $index -lt $element_count ]
do
  echo ${colors[$index]}
  let "index = $index + 1"
done
# Each array element listed on a separate line.
# If this is not desired, use  echo -n "${colors[$index]} "

echo

# Again, list all the elements in the array, but using a more elegant
method.
  echo address@hidden
# echo ${colors[*]} works also.


echo

exit 0

Fix:
        I sure wish I knew!!  if you can help me figure out why this works
on one machine but not the two with newer versions
        could you please let me know.

        Thanks,
