BD/PATCH Release 1.0 Quick Documentation OVERVIEW ======== BD/Patch is a versatile new utility from Breakthrough Designs for viewing or editing files, and other file-like objects such as disk drives, directories and memory. Patch supports various display formats to help interpret the data being edited, but removes the usual restrictions on file and disk manipulation usually imposed by DOS or applications programs. For this reason it is both a powerful and useful tool, and a good way to mess up data if you're not sure what you're doing. This program is a tool for patching files and data; the intelligence for what you are accomplishing is provided by you. WHENEVER POSSIBLE, ONLY PATCH A FILE FOR WHICH A BACKUP EXISTS. Patch is also a useful file or object viewer, to examine the structure of files or other data without making changes, and provides a good tool for seeing "what's inside" the data you examine. This program was created to fill several utility needs, and while this is the first commercial version of this program, it is the fifth major revision of a program which has been used profitably and powerfully by a number of people for over six years. Hopefully you will find BD/Patch a useful utility for your work as well. SYSTEM REQUIREMENTS ====== ============ BD/Patch requires an IBM-compatible computer running MS-DOS or PC-DOS version 2.0 or higher. Version 3.0 or higher is recommended. Patch utilizes as much base memory as is available, but requires at least 220K of free memory to operate. Any standard video display will work with Patch, although Patch has certain optional features which require an EGA or higher display. Also, Patch makes use of the extended keyboards (twelve function keys across the top) if you have one (and your system supports it). INSTALLATION ============ The programs and files of Patch all fit, uncompressed, on a single low- density floppy disk, and require less than 300K if installed on a hard disk. Simply copy the files from the Patch disk to a new floppy, or to a hard disk subdirectory. While the Patch files take up little space on a hard disk, you may wish to eliminate some files if you are adding Patch to a "utilities" disk. Only the PATCH.EXE file is required for operation. The following list describes the other files on the Patch disk, and what they are for: PATCH.HLP - the on-line help text. If removed, no help is available. PATCH.PRF - these are your preferences, if you have set any. If you remove this file, the factory defaults will be used. *.FS - any .FS file adds file system drivers. If these are removed, Patch will only have FILE, SUBDIR, LDRIVE and PDRIVE. *.CTL - any .CTL file adds display format drivers. If these are re- moved, Patch will only have HEX, TEXT, SUBDIR and LDRIVE. *.PRN - any .PRN file adds printer drivers. If these are removed, Patch will only have SIMPLE as a printer choice. QUICKREF.TXT - this document. README.TXT - quick description of the program and how to register. PATCH.PIF, PATCH.ICO - these are used by Microsoft Windows for infor- mation about this program, but are not required. RUNNING PATCH ======= ===== To start the Patch program, if you are in the directory where the Patch program is located, just type "patch" and press the ENTER key. Or, if you have from one to four files you would like to patch directly from the DOS prompt, type the names of these files after "patch," such as: C:\PATCH>patch \mainmenu.mdf a:\sample.dat If you want to patch a command from another file system, the format is the same but the name is preceded by the file system and a colon, like this: C:\PATCH>patch mem:286 subdir:a:\temp The number of files to patch you type specifies the number of windows which will be opened. If you start Patch without any named files, a single window appears with the "Opening Menu" displayed; choose options from that by pressing the desired letter, or use the pull-down menus instead. MS-DOS version 3.0 or higher is recommended if you run Patch from a different directory than you are working in, which is often the case. In MS-DOS version 2, Patch can locate the supplemental files if Patch was located in a directory specified by the path, and is still called "PATCH.EXE." But in MS-DOS version 3 or higher, Patch can locate the supplemental files based on how the command was started, regardless of what drive or directory the files are on, or what the Patch command is called. For example, if you had the Patch files on a floppy disk, you could type: C:\DOS>a:patch share.exe Patch would run, and find all its files on the floppy disk, but only if the DOS version is 3.0 or higher. Under DOS 2.x, you would have to make the floppy drive the active drive and run from there, like this: C:\DOS>a: A:\>cd patch A:\PATCH>patch c:\dos\share.exe BASIC OPERATIONS IN PATCH ===== ========== == ===== Patch was written to view and edit a variety of files, and file-like objects, in a consistent and editor-like way. There are two overlapping methods for controlling Patch, one based upon the WordStar editor, and the other based on cursor and function keys and pull-down menus, which have become customary elements in PC software. The cursor keys on your keyboard do pretty much what you would expect. The function keys are labeled at the bottom of the Patch screen by default (you can remove the labels if you wish). The pull-down menus are operated by pressing the ALT key and the first letter of the menu you want (these are displayed across the top line of the screen), and then selecting an option from the menu with the cursor keys and pressing ENTER on the one you want. Menu options may also be chosen by typing the capitalized letter on the option you want. The WordStar codes are faster to use and harder to learn. They all require a control code (press the CTRL key and the letter you want), many commands also requiring a second character which need not be a control code. The commands are represented with a carat (^) symbol to indicate a control code, so "^KX" means press Ctrl-K, and then X (which can be upper or lower case, or even Ctrl-X). If you are already familiar with the WordStar editor many of the commands will be familiar to you. If not, but you wish to learn them, the command reference in this document provides a list, or you can turn on WordStar menus by setting the help level to 3; this can be done with the command ^JJ3. Patch can edit up to four files at one time; each appears in its own "window" (a group of screen lines independent from the others). Only one window can be edited at one time, but the other windows continue to show what you are working on. The F10 key jumps between windows. Several commands for patching a file use "blocks," meaning a section of the file which you define and use as a single item for this command. In WordStar commands, you mark the block with the ^KB and ^KK commands, and then use a command to do something with that block. In the pull-down menus, on the other hand, you choose the command, and Patch prompts you to mark the length of the block (and, for some commands, where you want to use the block as well). For this reason the two sets of block commands are similar but not the same. Patch has a number of built-in display formats, and some standard add- on display formats. Built-in formats include HEX (displaying hexadecimal bytes and ASCII equivalences; this is the default), TEXT (a simple text editor screen, but awkward if your file isn't text), SUBDIR (the format for subdirectory data) and LDRIVE (the format for a logical drive). The file PATCH.CTL currently adds the DEC and OCT formats, which are similar to HEX but use decimal or octal, respectively. Patch has a number of built-in file systems, and some standard add-on file systems. Built-in systems include FILE (normal DOS files; this is the default), SUBDIR (DOS subdirectories), LDRIVE (a logical drive, named by its drive letter) and PDRIVE (a physical drive, named by its unit number). The file PATCH.FS currently adds the MEM file system, which patches the "files" BASE (1M of system base memory), 286 (16M of memory on a 286 or higher processor), 386 (4G of memory on a 386 or higher processor), and CMOS (the battery-backed real time clock and config memory in most AT compatibles). For printing, Patch can support several printer types, which are loaded from the file PATCH.PRN. Without the .PRN file(s), Patch only supports the SIMPLE printer type, which works suitably on any printer but doesn't make the same data distinctions one of the named printer types can. Other file systems, display formats and printer drivers can be added to your Patch program by simply adding the appropriate .FS, .CTL or .PRN files to the location of your existing Patch files. You can change many of the default options in Patch to suit your own preferences, and to configure Patch to your display if your computer will support 132-column text modes. These settings are all accomplished via the "Prefer" pull-down menu, and can be saved to the file PATCH.PRF to become your new defaults. PATCH PLUS Release 1.0 Command Reference Conventions: WordStar control codes are shown in "carat" notation, as in "^KX". Keyboard keys are shown in all caps, like "RIGHT" or "F10". Pull- down menu options are shown by their displayed names, inside angle braces, like "<File,Save>". For more help on any of these commands, invoke the Help system (F1, or ^Jc where c is a WordStar command).
