Description

National BASIC is a BASIC extension that is provided by the firmware of the FS-5500F1 and FS-5500F2 computers. This software needs to be enabled by a switch at the back of these machines.

Accurate infos about this firmware are missing, but it seems to be designed for the control of external devices during superimposing and digitizing operations, as these computers have two unusual connectors: alarm output terminal and system terminal (control output).

Instructions

This extension adds three new instructions.

Note: CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info.
