variable running once

[lerameur]

Hello

I just wrote a small script. I would like to know if the following is
possible:
I want to have some initial values like a time in the script. This
script is called from crontab every hour. These initial values should
be run only once when the script starts. Is there such a command in
perl ?
I thought of putting theses values in a separate file and when the
perl program starts, fetches those values and when it exist saves the
newest value so when it is called again it continues where it has
left off.

thanks
k

That's how you'd do it in any language. You have to store the
values somewhere because once the process exits, they're gone.

Are you looking for the time() function? perldoc -f time.

If not, please post a short-but-complete example of what it is you're
trying to do.
