Help on Shelling

The 'Shell' command is a very powerful but also very dangerous
command. It allows the caller to run a DOS shell on the sys-
tem, except that the caller receives the output, and the
caller enters the keystrokes.   The caller has complete control
of the HOST system at the DOS level.   Shell is a password
and level protected feature of HOST2.  The caller sees program
output only if the programs use standard DOS output. Programs
that write directly to the video screen will work, but will not
be seen by the remote caller. As well, programs that use non-DOS
methods of getting keystrokes will not receive the caller's
keystrokes. Finally, under some systems, if the caller presses
Backspace at the DOS prompt when the current line is empty,
DOS will hang on the Host machine. As these are functions of
DOS, there is nothing that can be done about these limits.
