I was told to write and edit files on the VRDC. How do I do that?

You could edit your programs from within the SAS graphical interface (see Question 2.11). That being said, the SAS Program Editor is not to be recommended under Unix in general. The preferable way to program is to

• write your program using other editors
• submit your program as a batch job

Editors can be found under N->Utilities->Editor. Your choice currently consists of

• GNU Emacs
• Kate

(both are graphical) and

• vi

as a command-line editor for the hard-core Unix fans out there.
