Comment:

What is the difference between
SET somevar=somevalue
and
@SET somevar=somevalue

Also, does anyone know how to display on the screen the value of a previously set environment variable?
many thanks

The @ symbol keeps the set command from echoing it's output back to the CRT.
To see what variables are set to, simply type,
set [enter]
at the DOS prompt.

@ECHO OFF also removes echoing of itself.
