%comspec% /v:on

Arcane, twisted, strange(hereafter referred to as "ATS")?   Welcome to my world.  However, some benefits:

-Logic is all "inline"
-Some constructs ~ problems become easier to resolve(at least for me--remember ATS).

In order to fully realize it's potential it's invoke DOS using delayed variable expansion.  Also, if
your making this a "startup" prompt for dos--use /k switch.

EXAMPLE

%comspec% /v:on /k (C:)
