tool. Modern versions of BASIC are even more simple to use than their forerunners; yet they now contain a variety of complex programming structures, providing virtually everything the professional programmer could ask for. Amongst the several BASIC versions currently available,
MIcrosoft's QuickBASIC 4.5 is probably the most the most widely used and certainly the most effecient. It can be used be used to write all types of program and its flexibility gives it an edge over other, more specialized languages in a wide range of programming situations. This book takes the user from the initial installation through the stages of program design and structure, the command language and its use, operation and program debugging. By the end of the book the reader should be proficient in the operation of the QuickBASIC programming language and able to construct sophisticated programs. The emphasis is on showing how to build effective programs through the use of meaningful exapmles. Coverage includes QuickBASIC more advanced features as well as the standard BASIC facilities. The book has a single, main theme: the creation of a program to record, cross-reference and display local
history data. This example has been chosen because it incorporates most of the principles neede for a whole range of programming situations. While the finished product may be of little use to the majority of programmers, the program has been designed on a modular basis. Each module is typical of the activities required in thousands of otherr
applications: selecting from menus, text-file handling, record-based data, manipulating dates and other data types, simple graphics, and so on. Therefore there are many sections of the sample program that cen be adapted and @#p£×=qÿ¾Û€
