Turbo Basic

FilesOnce you have created a program or a collection of data that you'll need to accessagain, the next logical step is to save it. In saving your data, you are creating a filethat can be used for input or output. There are three file types you can create:sequential, random access, and binary. We'll discuss each of these types here, butfirst let's look at how to name files and/or directories (which contain several files orsubdirectories).As a citizen of an MS-DOS world, the files you create and access using TurboBasic must conform to DOS naming conventions. File names consist of two parts,separated by a period:filename. extwhere filename can be from one to eight characters, and ext is an optional typeextension of up to three characters. If a file name is longer than eight characters,Turbo Basic automatically truncates the name and adds a period at its end. Forexample, if you enterTESTINGOATAit becomesTESTINGO.If a string has a period that separates the file name and its extension but the filename is over eight characters long, Turbo Basic truncates the name to eight charactersand then appends the extension, like so:VERYLONGFILENAME.TBSbecomesVERYLONG.TBSIf you use an extension with more than three characters, the extra characters aretruncated; for example:TESTING. DATAbecomesTESTING.OATFile names and extensions can contain the following characters:A-Z 0-9 ( ) { } @ # $ % - & ! - _ ' / -96 Turbo Basic Owner's Handbook
