How do I run this .VLX program?

[Cadastrophic]

I have a program that I want to try out. It's called cylinderD.VLX. I've loaded it successfully, but don't know how to run it. I've tried typing its name in the command line, but this doesn't work.
Can anyone tell me with the procedure please?

try loading it again and keep an eye on your command line ~ it should tell you what to type to run it. Hit F2 if needed.
Since it's a VLX, you won't be able to get to the source code to see what the command is.
do you have any other documentation with it ? whoever supplied it should have included a text file or something

A good program should tell you how to start it :(
