Quick Start

COM file format:

zcc +cpm -lpx4  -create-app -oname name.c

zcc +cpm -lpx4  -create-app -oname name.c -pragma-need=ansiterminal -pragma-define:ansipixels=240 -pragma-define:ansicolumns=60

ROM file formats:

zcc +cpm -subtype=px4  -create-app -oname name.c

zcc +cpm -subtype=px4ansi -create-app -oname name.c -pragma-define:ansicolumns=60

The VT/ANSI console driver

The ANSI VT emulation can work in several column size variants:

''-pragma-define:ansicolumns=30''

''-pragma-define:ansicolumns=34''

''-pragma-define:ansicolumns=40''

''-pragma-define:ansicolumns=48''

''-pragma-define:ansicolumns=60''

''-pragma-define:ansicolumns=80'' (barely readable)

''-pragma-define:ansicolumns=120'' (almost useless)

Emulator Links

The HC-40 Takeda's emulator can be used to test the programs by creating a 32K ROM image (use the "-Cz--32k" if necessary) and renaming it to "BASIC.ROM".
