This manual introduces the idea of using BASIC as an operating system as well as a programming language. This way, BASIC, can be used to set up communication links, to send and receive data along them and to manipulate files. This adds enormously to its power to perform tasks in which:
data is stored and retrieved
data and programs are sent to peripherals
communication links are established with other Spectrum computers or with other types of computer.
The combined use of BASIC as an operating system and a programming language gives it a power and flexibility, and also an ease of use, to be found in few larger computers.
This manual should only be read after you have familiarised yourself with the ZX Spectrum Introduction booklet and with chapters 1 to 22 of the BASIC programming manual.
