This programming language may be used to instruct a computer to perform a task.
If you know Sinclair ZX81 BASIC, please write code for some of the tasks not implemented in Sinclair ZX81 BASIC.
Sinclair ZX81 BASIC is the dialect of BASIC resident in ROM on the ZX81 home computer (1981) and compatibles (Timex Sinclair 1000, Lambda 8300, and many others). It was developed by John Grant and Steve Vickers. Today, ZX81 emulators exist for a wide range of platforms and operating systems.
ZX81 BASIC is almost a subset of ZX Spectrum Basic, but not quite: the exponentiation operator is spelled
** rather than
↑ (mapped to ASCII
^), the unconditional jump and subroutine call keywords are spelled
GOSUB rather than
GO TO and
GO SUB, etc. Note also that the ZX81 uses an idiosyncratic (non-ASCII) character set, so that the
CHR$ functions do not return the same values as they would on the Spectrum. Floating point operations, some string handling, and low-resolution graphics are supported; colour, sound, user-defined functions, the
RESTORE keywords, and assorted other features are not.
