^C^1RESICALC HELP ^C^1Introduction ^C^1------------ ResiCalc is a handy "pop-up" calculator that will give you full use of your keyboard's number pad while you are at the DOS prompt or from within any 80 column text-mode program. This type of memory resident utility is called a TSR. ^C^1What is a TSR? ^C^1-------------- The acronym "TSR" is short for "terminate and stay resident." In plain English, this means that once ResiCalc is loaded into your computer's memory, it will be available whenever you need it. Many TSRs will not run unless they are loaded into memory. When they are loaded, they "tie up" part of your computer's RAM or random access memory--memory which is no longer available for use by your other programs. Therefore, some computer owners avoid TSRs. There is no reason to avoid ResiCalc, which gives you several different "run" options. ^C^1Loading or Installing ResiCalc ^C^1------------------------------ There are three ways you can use ResiCalc: (1) as a TSR that is available upon bootup (add ResiCalc to your AUTOEXEC.BAT file); (2) as a TSR that you load into memory and remove from memory on the fly from the DOS command line; and (3) as an ".EXE" file (run it without making it resident). You must decide which is best for you and your computer. Then follow the instructions below that correspond with your choice. ^IHOW TO MAKE RESICALC RESIDENT UPON BOOTUP STEP 1: Copy ResiCalc into a subdirectory that is in the PATH statement of your AUTOEXEC.BAT file. If you don't know which subdirectories are in the file, type "PATH" at the DOS prompt and note the list of subdirectories following the word "PATH." STEP 2: At the root directory prompt in DOS (usually C:\), type "COPY AUTOEXEC.BAT AUTOEXEC.RES". This will create an extra copy of your file so that you can restore it (revert) later if necessary. To restore your old AUTOEXEC.BAT, type "COPY AUTOEXEC.RES AUTOEXEC.BAT" and reboot your system. STEP 3: Add ResiCalc to your AUTOEXEC.BAT file by using the built-in DOS editor (type "EDIT AUTOEXEC.BAT") or a simple text editor such as Edit Meister (issue #72). Add the following statement to your AUTOEXEC.BAT file: "RESICALC". NOTE: The DOS EDIT command is available in DOS versions 5.0 and later. We recommend that you add the statement AFTER your "PATH" statement, AFTER any other TSRs, but BEFORE any statements that launch "shell" programs such as Windows. Also, LSHIFT+CTRL is the default hotkey. If you change the hotkey (as explained later in this document), you must use that hotkey in your AUTOEXEC.BAT. STEP 4: Save the updated AUTOEXEC.BAT, exit to DOS and reboot your computer. ResiCalc is now installed as a TSR and will be available from DOS or from within any 80 column text-mode program. NOTE: It will not activate while you are running a graphics program. ^IHOW TO LOAD THE PROGRAM INTO MEMORY ON AN INTERIM BASIS STEP 1: Change to the subdirectory of your hard drive or floppy drive where ResiCalc is located. At the DOS prompt (for example, C:\ODM76), type "RESICALC". ResiCalc will load into your computer's memory, and will remain in memory until you remove it (See Removing ResiCalc from memory) or until you re-start your computer. STEP 2: Press the default hotkey (the Left Shift and Control keys at the same time). The ResiCalc calculator will "pop" onto your screen. NOTE: It will not be available the next time you boot your computer. To load ResiCalc again, follow these two steps again. Also, if you want to use a different hotkey, see Command Line Options below for help. ^IHOW TO RUN RESICALC WITHOUT MAKING IT MEMORY RESIDENT STEP 1: Change to the subdirectory of your hard drive or floppy drive where ResiCalc is located. At the DOS prompt, type "RESICALC /N". The ResiCalc calculator will appear on the screen. This command line option, "/N," refers to "non-resident mode." NOTE: You cannot access ResiCalc in this manner while running another program. If you wish to activate ResiCalc only when using certain programs, follow the Interim instructions above. ^IREMOVING RESICALC FROM YOUR COMPUTER'S MEMORY (De-Installation) STEP 1: At the DOS prompt, type "RESICALC /R". NOTE: Your computer will not remove a TSR unless it is the last TSR that was installed. If you have installed other TSRs since installing ResiCalc, you must first de-install them (in an order that is the exact reverse of your installation order). ^C^1How to Use ResiCalc ^C^1------------------- Visually, ResiCalc looks like a standard hand-held calculator and will operate in much the same way. ResiCalc does not have mouse support, but it is a snap to use with your number pad or arrow keys. To activate your keyboard's number pad, "turn on" your keyboard's Number Lock by pressing the "Num Lock" key. Most keyboards have a status light to show when Num Lock is "on." You will see a corresponding highlight on the Num Lock button on the ResiCalc calculator on your screen. You may use your keyboard's arrow keys to highlight the calculator button you want to use. Press Enter to activate it. You may also use one of the special keys shown below to activate the calculator keys: Note: Numbers in ResiCalc are limited to four (4) decimal places. F1..............Help Back Space......Deletes character to the left of the cursor Num Lock or N...Toggles Num Lock (white=active, black=not active) S...............Selects +/- (toggles between positive/negative #) P...............Adds current number to memory (M+) M...............Subtracts current number from memory (M-) C...............Clears memory (MC) R..............."Recalls" number in memory for use by calculator A...............Clears all calculations (CA) E...............Clears current entry or number (CE) Enter...........Accepts calculations (acts as the equal sign) or carries out the function of a highlighted button (flashing text indicates highlight) Escape..........Exits program or closes Help screen. ^C^1Command Line Options ^C^1-------------------- At the DOS prompt, type: RESICALC /?.....To access this list of command line options RESICALC /N.....To run ResiCalc in non-resident mode (like an executable program or .EXE), so that it is not installed in your computer's memory RESICALC /R.....To remove ResiCalc from memory (see "Removing ResiCalc From Memory" above for details) RESICALC /V.....To display version and author information RESICALC /KEY=..To change the hotkey designation NOTE: The hotkey is composed of two parts: one or more of the following keys--right shift (RSHIFT), left shift (LSHIFT), Alt (ALT) or Ctrl (CTRL); plus any single letter, number or function key(F1-F10). You MUST include the first part when you alter the hotkey, but the second part is optional. If you use RSHIFT+LSHIFT in the first part of the hotkey, you cannot specify a second part. If you do not specify the first part of the hotkey, LSHIFT+CTRL will be used by default. For example, to change the hotkey to Ctrl/Alt/F10, you'd type "RESICALC /KEY=CTRL+ALT+F10". Use plus signs and no spaces between specified keys. Also, you can change the hotkey AFTER ResiCalc has been installed in memory, so if you forget your hotkey, just make a new one!
