NEWB: how to reset $1 in multiple calls to scripts

[misterstick]

AIX 4.3.3
i have a script which i wish to run with and without parameters.
when run without, it should use a default value.
when i run the script first with a parameter, and then without, the second time the script behaves as if there were still one parameter.

example script:

!#/bin/ksh
echo $# $1

example session:

$ . script.sh parameter
1 parameter
$ . script.sh
1 parameter
$ echo $# $1
1 parameter

is there any way to stop this behaviour?
many thanks,



mr s. <

You're setting $# and $1 in your current shell by executing script.sh using the dot (.) command.

Make it executable so it runs in a subshell...
