INPUT allows data
to
be entered
Into
a SuperBASIC program directly from the OL
keyboard by
the
user.
SuperBASIC halts the program
until
the
specified amount
of
data
has been input;
the
program
will
then continue. Each
item
of data must be terminated
by
the
ENTER
key.
INPUT
will
input data from either the specified or
the
default channel.
If
input
is
required
from
a particular console channel
the
cursor
for
the
window connected
to
that channel
will
appear and start
to
flash.
