-
- Douglas Boling 1988 No. 5 (Utilities)
-
-
- Purpose: A pop-up programmer's calculator with base conversion,
- bit-shifting, logical operator, and mod functions, and 32-bit number
- representation that also supports a 2-decimal place integer arithmetic
- calculations.
-
- Format: [d:][\path]CALC
-
- Remarks: CALC is a terminate-stay-resident (TSR) program that can be
- loaded either at the DOS command line or as a part of an AUTOEXEC.BAT file.
- The Alt-S key combination (default) pops up a 6-line window for calculations;
- the Esc key restores the screen to its previous condition. The program
- accomodates automatically to monochrome, CGA, or EGA displays.
-
- Any number on CALC's entry line can be successively converted to
- hexadecimal, binary, octal, or decimal (default) notion by pressing F1.
- Mixed-base calculations are supported, and the +, -, *, and / function
- conventionally so long as it is realized that CALC operates in integer, not
- floating point mode. (Fixed 2-decimal place calculations can be made by
- pressing F2 before entering the numbers.) In integer mode the mod function
- (e.g. 25 mod 8 = 1) is also supported, using either the % or the \ sign as the
- operator.
-
- CALC uses full 32-bit number representation, and so can be used for
- address calculations. The function keys F3, F4, and F5, perform logical and,
- or, xor operations between two numbers. F6 performs a not (invert) function on
- the number entered. F7 shifts bits left and F8 shifts right. F9 is a
- change-sign key, and F10 clears the entry line. To clear the calculator field,
- press Shift-F10.
-
- Instructions on modifying the default hot-key and colors are presented,
- with appropriate tables of possible values, in a sidebar to the main article.
