Gosubs: 100 Program-Building Subroutines in Timex/Sinclair Basic (McGraw-Hill/VTX Series)

Here in one book is a useful library of subroutines in Timex/Sinclair BASIC, the programming language built into the Timex/Sinclair 1000 and 2000 computers. The subroutines have all been fully tested, and are ready to be put to work immediately within larger programs in order to perform computations in statistics, geometry, finance, program control, or conversion. The subroutines are clearly explained for the novice, who should also be helped by the general introduction to the subject of subroutines in the first chapter. Unusual and hard-to-follow routines are clearly explained, and suggestions are made about the best techniques for writing original subroutines.
