Like most home computers at the time, the CPC has its [[operating system|OS]] and a [[BASIC interpreter]] built in as [[read-only memory|ROM]]. It uses [[Locomotive BASIC]] - an improved version of Locomotive Software's Z80 BASIC for the [[BBC Micro]] co-processor board. It is particularly notable for providing easy access to the machine's video and audio resources in contrast to the [[PEEK and POKE|POKE]] commands required on generic Microsoft implementations. Other unusual features include timed event handling with the AFTER and EVERY commands, and text-based windowing.
