P-BASIC is a BASIC extension created by Pioneer to control LaserDisc players and the superimpose features of the Pioneer machines.

'There are two versions of P-BASIC, 1.0 (c) 1984 and 1.1 (c) 1985. The difference between the versions is unknown. The following MSX1 systems feature P-BASIC:

P-BASIC Version 1.0

P-BASIC Version 1.1

In addition P-BASIC 1.0 is also provided by the Pioneer ER-101 Expansion Processor.


P-BASIC adds 18 new instructions, that can be generally divided into four types of functions.

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