Calling variable from another script

Can someone help me understand how to pass a variable to another test using JAVA SCRIPT in TEST COMPLETE?

How can I create another script (Unit2) that will use the value stored in MyFolderName created in Unit 1?

Use Case from Unit 1 

1. User clicks on the create button on the GUI => a folder is created and a test.txt file is created.
2. Find what folder name it is and store it in "MyfolderName" and search in that folder for test.txt
3. Next call Unit2  (see below)

<Repeat test Unit 1>

1. User re-clicks on the create button on the GUI  => a 2nd folder is created and a test.txt file is created.
2. Find what folder name it is and store it in "MyfolderName" and search in that folder for test.txt
3. Next call Unit2  (see below)
4.  

User Case from Unit 2

1. Take folder1, create a readme.txt and write to the file
2. Take folder2, create a readme.txt and write to the file
3.  

Please excuse me, I am just learning, and providing a sample will greatly help me understand it.   

Your help is greatly appreciated.
