MAKING MATHS EASIER A program which appears to defy the rules of mathematics has been added to the Video Software range of 'serious' software for the ZX-81. Called Video-Index, the maths-defying element is the fitting of 57,000 characters of data in a 16K memory, which is achieved by an ingenuous technique whereby duplications of descriptions are detected and eliminated. Written largely in machine code for speed, Videoindex provides a technique for using the ZX-81 to build a catalogue or index which can be stored on cassette and re-used. The program, which is supplied with a demonstration index of computer magazine articles about the ZX-81, costs £9.95 and can be obtained from Video Software, [redacted].
