Line 1:
'''BASIC toolkits''' (aka ''BASIC extensions'') - not to be confused with [[toolkit|widget toolkits]] - were a common type of program for 1980s 8-bit [[home computer]]s. Generally third-party extensions, they added additional features to the built-in [[BASIC programming language|BASIC]] [[interpreter]].
Toolkits ran as [[terminate and stay resident]] extensions to the BASIC interpreter supplied with the machine. At the time, such interpreters almost always came programmed into the [[Read Only Memory|ROM]] of the computer, making it impossible to modify or [[Patch (computing)|patch]] the [[computer code|code]]. It was also extremely rare for manufacturers to offer upgrades or bugfixes except as part of new models of machine. Typical toolkit functionality included editing extensions, such as commands to renumber a program, perform block line deletions and so on, and additional keywords to perform new functions.
Line 7:
The [[Beta BASIC]] extension to [[Sinclair BASIC]] on the [[ZX Spectrum]] computer started out as a simple toolkit but grew into an interpreter in its own right.
