Messing with environment variable

[FORAND]

How can i :

Change a system (or user) environment variable (on NT) and use that variable in my program ?

Do I have to close and re-open my program to do so?? ?

Please help, i'm desperate....

You can set the env. var. in controlpanel / system (If I remember right), and read the variable in processes (your programs) *created* after this.

Use getenv() to read the variable.
