The environment variable is a global variable, holding QTP "system" values, as well as user defined values.

You can access the environment variable from anywhere in your script:

Msgbox Environment("Some Name")

Where "Some Name" is the name of the item you want.
For example:

Msgbox Environment("TestName")

Will print the current test name.

You can easily add new items to the environemnt:

Environment("Some Name") = "Some Value"

We usually use the environment variable in one of two cases:
1. We wish to access some QTP "system" data (e.g. the name of the test). You can see all the system items of the environment variable by going to File->Settings->Environment

2. We wish to store data that will persist and will be available from different actions, iterations and functions.
