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 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 control characters such as CTRL—M (carriage return).
CTRL-Y CTRL-I changes back to command character CTRL—I.
The values and conditions listed below are the values which are automatically set any time the Grappler is “turned on” with a PR#n command or initialized from Pascal or CP/M:
Left Margin | = Ø | Right Margin | = Ø |
Line Length | = Ø | Page Length= Ø | |
Video | = On | Printer Bell | = Off |
Eighth Bit | = Off | Line feed after | |
| | carriage return? = Yes with Basic |
No with Pascal or CP/M
