set issue on ksh

Want to have an array in ksh
$which ksh

$set -A a1 v1 v2
$echo $a1[0]

Everything seems fine.

I wrote it to a script like s.ksh,
$cat s.ksh
set -A a1 v1 v2
echo "1=${a1[0]}"

If I ran it, I got the error.
s.ksh: line 2: set: -A: invalid option
set: usage: set [--abefhkmnptuvxBCHP] [-o option] [arg ...]

Can any gurus shed some light on it? How to fix it?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Which way did you run the script?

If you ran it with

sh s.ksh

then the shebang line will be ignored and the interpreter "sh" will be used, whatever it is (looks like bash).

What do you get with

sh --version
