Description

Lightpen Graphics is a drawing program written by HAL Laboratory and used in several Sanyo products. It requires a lightpen and comes with a MSX-BASIC extension called Expander BASIC.

There have been several releases of this utility:

• on tape and provided with the MPC-10 and MPC-11 computers (probably without the MSX-BASIC extension)
• on cartridge and included with the KA-MPC-X package for the MPC-X Graphic Expander Unit
• built-in in the MPC-10mkII computer and the following peripherals:
  • Sanyo MLP-01
  • Sanyo MLP-001

This utility 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).

Note: The Daewoo DLP-01 cartridge includes a different drawing program although having the same name and manufactured also by Sanyo. It is unclear if the Expander BASIC is available in this cartridge.

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.
