WRITING

SYNTAX

   WRITE {[mode]},{[parts]}

PURPOSE

The WRITING command is used to control how the text is presented on the screen. The first value selects one of five writing modes:

* REPLACE (0) – new text replaces any existing screen data; * OR (1) – merge new text with screen data, using logical OR; * XOR (2) – combine new text with screen data, using XOR; * AND (3) – Combine new text and screen data, using logical AND; * IGNORE (4) – ignore all subsequent printing instructions.

A number set as the optional second value selects which parts of the text are to be printed on the screen, as follows:

* NORMAL (3) – Print text and background together; * PAPER or PAPER ONLY (1) – paper only the background to be drawn on screen; * PEN or PEN ONLY (2) – ignore paper colour and print text on actual background.

The default value for both of the WRITING parameters is three (3), giving normal printed output.
