From: Edward Haines <haines@BBN-UNIX>
There are several new reserved words in BASIC Release 2.0 that are not
documented: ENVIRON, ENVIRON$, ERDEV, ERDEV$, INTER$, IOCTL, IOCTL$,
KEY$, and SHELL.
ENVIRON "X=value" command - sets environment variable X;
like DOS SET X=value
ENVIRON$("X") function - returns value of environment
variable X.
ERDEV, ERDEV$ ?
INTER$ ?
IOCTL, IOCTL$ access to the IOCTL functions in DOS (?)
see DOS pages 14-7 and D-39
KEY$ ?
SHELL command - takes you to DOS command
level; return to BASIC with EXIT.
SHELL "command" command - execute the specified DOS command
and return immediately.
