Description
Expander BASIC is provided with Lightpen Graphics, a drawing program for lightpen, written by HAL Laboratory and used in several Sanyo products.
There have been two versions of this utility:
- Version 1 (probably without the MSX-BASIC extension)
- on tape and provided with the MPC-10 (version 1.0) and MPC-11 (version 1.1) computers
- built in the Daewoo DLP-01 peripheral
- Version 2
- on cartridge and included with the KA-MPC-X package for the MPC-X Graphic Expander Unit
- built in the MPC-10mkII computer and the following peripherals:
Version 2 allows to save your drawings in a MSX-BASIC program that can be runned only when the cartridge is in a slot, because some additional instructions are used to recreate the product of your artistic work.
You can also optionally write directly programs using these instructions when the cartridge is present. When you choose 'MSX-BASIC' in the main menu of this utility, the Expander BASIC is indeed available for using (even without lightpen).
Instructions
The Expander BASIC extension adds four new instructions.
Note: CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info.
