unaltered form, and accompanied by this text file, subject to the
conditions above.
Registered users will receive the latest version of the program, a
Help screen file accessible from within the program, and complete
documentation that includes detailed command examples and a table
of operators with their respective functions, AND a handy imitation
vinyl carrying case with belt loop (just kidding - no carrying
case). You will also be supporting the Shareware concept, future
program developments, and helping to convince my wife that this
whole idea really does work!

PROGRAM DESCRIPTION
This function simulates a simple "feet-and-inch" calculator that
accepts input in standard AutoCAD Architectural units. It provides
addition, subtraction, multiplication, division and conversion
operations for both linear foot and square foot "units", including
fractions as small as 1/64". The only prerequisite is that the
current drawing units be set to "Architectural" (Option 4).
The program is designed to use the numerical keypad as much as
possible. A Help function is available to registered users that
will display a complete table of operations, the options
available for each operation, and helpful tips.
BACKGROUND
I am an architect, not a programmer, and I developed this program
to fill a need for architects and all others who work with standard
construction increments of feet, inches and square feet. It is
loosely based on the stand-alone "feet-and-inch" calculators
commercially available for $70 to $80.
ARCHCALC will not figure compound interest, orbital descent, or
seismic stress on structural members, nor is it intended to. I
left out some possible options to maintain a reasonable function
size and keep the program fast. The program has been tested and is
currently in production use on 286 and 386 machines. I hope some
of you find this program useful, and I welcome any and all comments
and suggestions you might have.
INSTRUCTIONS
Numbers are entered and stacked similar to the Hewlett-Packard
calculator format. The [Enter] key must be pressed after each
number and operation. Each operation will be applied to all
numbers in the current stack. The number resulting from each
operation is also pushed onto the stack. Results are cumulative
until using the Clear function, which clears the stack completely.
COMMAND FORMAT
The ARCHCALC command always displays two command prompt lines that
list each available command option. Just type the capitalized
letter or appropriate characters (+, -, /N. etc.) to choose an
operation. You must press [Enter] after inputting each operator or
number. The prompts are:
[Special Operations: ** (LfxLf=Sf) // (Sf/Lf=Lf) /N (f/f=#) D
(decimal ft) ]
Clear/Quit/Help/Linft/Sqft/operation above/+ - * /, or number:
