This book describes the QuickBASIC dialect which is one of the two most popular structured dialects of BASIC running on the IBM and compatible computers. QuickBASIC statements are introduced and explained with the help of simple programs. This enables the use to build up a considerable library of their own programs and procedures which become the building blocks of advanced programming techniques. The book explains: how to use the QuickBASIC environment and Editor; how to format Print statements and use Input, Read,and Data statements; how to control program flow with the for...next, do, while...wend loops, and the use of the block IF set of statements; how to use starting variables, string arrays and subscripted variables in alphabetical sorting using the bubble sort technique; how to use the standard BASIC functions; how to write modular programs exploiting user defined functions, procedures an and subroutines; how to use sequential and random access files; how to write a general program that can create and retrieve any random file which becomes the basis of database design.
