lines per page (this may vary with the type of
printer). Therefore if you specify a printed
page length of 6Ø lines (CTRL—I 6ØP), your
printer will print 6Ø lines and automatically
skip over the perforation with 6 line feeds.
CTRL—I B Turn on bell. This allows a CTRL—G to ring the
printer bell. Many printers do not have a bell
so check your printer manual to see if this
feature is available.
CTRL-I C Turn off bell.
CTRL—I S Duplicate the present text screen on-the printer.
The screen will be printed 20 spaces from the left
edge of the paper. This command is accessible from
BASIC only as it uses some of the monitor
routines, Only the forty character screen is
printed. Eighty character boards are not
supported.
CTRL—I CTPL-Y Change to new command character CTRL—Y. To do this,
type in CTRL-I CTRL-Y. Any control character may be
used here (instead of CTRL—Y) but you should avoid
characters used by your printer or normal text con-
trol characters such as CTRL—M (carriage return).
CTRL-Y CTRL-I changes back to command character CTRL—I.
