19) Carriage Return

VDU1, 13

Performs a single line feed

20) Audible Alarm

VDU1, 7

Activates audible alarm lasting about 300msec.

21) Clear Printer Buffer

VDU1, 127

Clears print buffer and resets print head. Does not affect tab programs etc.

22) Plotter Programming

Although it is possible to program graphics dump routines in BASIC the result would be very slow due to the large amount of information that must be processed. Any routine of this type should therefore be written in machine code. Such a "Printer Dump Routine" is available from Acorn for the JP101.
