After downloading the file here, extract the contents of the zip file into the "System" sub-folder, found in the directory you originally installed Textpad to.

To Set it up:

• Open textpad and go to “Configure” then choose “New Document Class”.
• A window should appear with the text: Document Class Name, and a box beside it. Type in “VC” and click next.
• On the next screen, in the box beside “Class Members”, type “*.vc” (without the quotes, so, asterick dot vc), then click next.
• On the next screen click the box that says “Enable syntax Highlting” and then in the dropdown menu look for “vc3.syn”. Click next.
• On the next screen double-check and make sure everything is correct, and then click Finish.

You may have to restart the program for it to take affect, however, now whenever you open a .vc file with textpad, you will see a bunch of different colours, which will help you to distinguish the different parts of your code.
