Positional Parameters (arguments)

Can positional parameters in korn be resetted?
What I mean is, if I have a script that takes 3 srguments:

$ myscript arg1 arg2 arg3
...script runs and so $1 is equal to arg1; and $2 is equal to arg2, etc...

When I ran it again WITHOUT provide any arguments:

$ myscript
...

It runs with the previous arguments still in effect.

Is there a way to keep that from happening in Korn?

I know in bash, that does not happen.

I never saw nor can reproduce this behaviour.
Actually I could only explain what you describe if "myscript" is implementing some kind of persistance.
Can you send your script ?
Are you sure you use a "real" korn shell ?

Nevermind... I just discovered what I was doing wrong.

I was "sourcing" the file instead of "executing" it (if that IS the proper term).

I was doing this:

$. ./myscript arg1 arg2

instead of

$./myscript arg1 arg2

I now know that there is a difference when it comes to environment variables.

Forgive me, I'm a newbie to scripting.
