PipeDream can be used to carry out most of the operations you are likely to want to perform on text and numbers, such as entering and editing, searching, sorting and calculating. However, some problems would require you to carry out, a sequence of different operations and this might be cumbersome and time-consuming using PipeDream. For this sort of problem you can turn to the BBC BASIC programming language which is provided in your Cambridge Z88.
Programming languages are designed to allow you to instruct the computer to carry out a sequence of operations on text or numbers. BASIC is one such general-purpose programming language, and is the most widely used language on microcomputers. BASIC has a significant advantage over many other languages in that it is interactive: you can make changes to a sequence of instructions, and see the result immediately without having to perform any intervening operations. This means that programs can be developed relatively quickly.
