OK!

A little background; I work in a company that gives IT services to about 50 companies. I made a script that should run only on those companies servers and that will notify us by mail [BLAT] if those servers free hard disks space is less than 10% from it's all capacity.

To make it easier let call this script "PROCESS", and the other script i'm looking to write will be "CONFIG".

Now, the script [PROCESS] run just fine, i have tested it on one company. Since every company has its own mail server, i was looking for an easier way to make the changes, such as: mail server name, mail sender address, etc. Instead of making those changes manually in the script [PROCESS],
The idea i had is to have another script [CONFIG] that will run only once in each company by our technicians and will ask them for the relevant information and will make those changes in the script [PROCESS] that will run by schedule one or twice a day.

Some of the solutions i have received here were by using an INI file and configure an enviroment variable with SET command that can be done from the script too.

Everything is clear to me [thanks to everybody here] but i can't realy understand how to do it. How to set this variable, how to write it, what the exact syntax? It doesnt matter that i will use this method on each and every company, i intend to make this SET thing by kix.

I hope that this will help you guys to help me :-)

p.s.

You guys doing a great job :-)
