II Plus users have made the required replacements, they likewise may notneed or want further changes. However, the arrangement of files on yoursystem disks is by no means fixed.The optimal arrangement for you may depend on how you intend to usePascal. If your system has only one 51A-inch disk drive, you may need torearrange files or create special disks. Once you learn which system filesare necessary to perform which Pascal tasks, the rest of the decision isyours. See "System Files as Required by Pascal Commands," inAppendix 2B, to learn which Pascal commands require which system files.When making custom disks, you will need to use the Filer's Transfercommand to move files from one disk to another, the Filer's Removecommand to remove unnecessary files, and the Filer's Change command tochange the names of files and disks. Filer commands are explained inChapter 3 of Part ILNote that SYSTEM.FILER, the file that contains the Filer program, resideson APPLEl:, APPLEO:, and lPASCAL:. However, SYSTEM.FILER does notneed to be available to the system once the Filer command line is displayedon the screen. Thus, when using the Filer to rearrange disk files, you can dothe following:1. Start up your system as usual.2. Press F to enter the Filer.3. If necessary, remove APPLEl: (or APPLEO:) from the startup drive tomake room for other disks.4. When you want to return to the Command level, place APPLEl: (orAPPLEO:) back in the startup drive and press a for Quit.If you have one 51A-inch disk drive, the next section and Appendix 2Bprovide the information you need to decide on the best configuration of files.Apple Pascal System Disks and FilesThe disks that contain the programs making up the Apple Pascal systemare called the system disks. The files on those disks are called system filesor program files; a distinction is often made between the files whose namesbegin with SYSTEM. and the other Pascal files. The SYSTEM files are thosethat are essential to run the basic programs that constitute the Pascalsystem. Many of the other Pascal 1.3 files are utility programs and in thelargest sense are part of the Apple Pascal system. A few demonstrationprograms account for the remaining files included with Apple Pascal.1-30Getting Started
