Calculator was written by: Leland C. Sheppard Sheppard Software Company 4621 Luneman Road Placerville, CA 95667 Phone: (916) 621-4685 (BBS - 8AM to 11PM Pacific time) CIS ID: 70574,2146 The Calculator program is shareware. If you use the program regularly and are interested in having us continue to develop it and other such programs, you should register the program with us. You may register Calculator for $4.00. In order to register, fill in the Register.Txt form, make out a check payable to Leland C. Sheppard and mail both to the address shown above. Calculator was written in VX-REXX 2.1 and requires the VX-REXX 2.1 (or higher) runtime module (VROBJ.DLL) in order to function. Also, REXX and REXXUTIL must be installed on your system; both REXX and REXXUTIL come with OS/2. File CLCARR.ZIP contains the VROBJ.DLL module; file CLCATR.ZIP does not. Only one copy of VROBJ.DLL is required for all of the VX-REXX programs on your system; if you have previously downloaded a copy of it, you do NOT need to download it again. HOW TO OPERATE CALCULATOR: Key Mapping: 0-9 . / * + - % = - face value on the numeric keypad or main keyboard section MR - F5 - Memory Recall M+ - F6 - Memory Add M- - F7 - Memory Subtract MC - F8 - Memory Clear CE - E - Clear Entry C - C - Clear All Get - G - Get number from clipboard Put - U - Put number on clipboard Pr - P - Toggle Print on or off The top box (list box) contains current and prior activity on the calculator from the time the program was last started. You can scroll this window using the keyboard (the arrow keys, Home, End, PageUp, PageDown) or your mouse. If you scroll the list box with your mouse or keyboard, you will need to manually return the focus to the keyboard to continue entering calculations. The simplest and cleanest way to do this is to click on the "=" key. If you enter an erroneous digit, you can use either the BackSpace key or the Del key to remove the bad digit. If you want the contents of the "tape" put in a file which can be printed, press P or click on the Pr button. Each time you press this button or the P key, you will turn "printing" to a file on or off. The default print file name is "Calclatr.Prt". If you want to specify a different file name and/or want printing to always be on, you can supply a file name on the parameter line (in the settings box or on the command line) when you start Calculator; for example, "Calclatr myfile.txt" without the quotes. If you want to copy the number in the Number Entered/Result window to the clipboard, press U or click on the Put key. If you want to copy a number from the clipboard to the Number Entered/Result window for use in the current calculation, press G or click on the Get key. Double click on the button in the upper left corner of the Calculator window or press Alt-F4 to end Calculator. Thank you for your interest in our software. Leland C.
