This is a programmable arbitrary precision RPN (reverse polish notation)
line oriented calculator for Windows 3.1, which includes financial and date
functions in addition to many standard mathematical functions. The extended
precision math routines utilize Judson D. McClendon's Bigcalc extended
precision library. Virtual arrays are used for the stack and memory
registers, so there are no effective limits on the stack size or number of
registers. One register requires slightly more than 1K, so 1.1MB of disk
storage will suffice for 1000 registers. The stack is based on the FORTH
model rather than the HP calculator model; that is, the stack expands and
contracts as numbers are entered or result from operations upon numbers
already on the stack. Programs for the calculator use a notation that is a
hybrid between that used in the HP-41 calculator and FORTH. Programs can be
written using any editor, such as Notepad. A number of sample programs are
provided. Calculator dialogs are provided to facilitate use of the financial
and date functions. The date calculator dialog provides the option of passing
the calculated date through the clipboard to a calendar program such as
Calendar, using the PC Magazine Wincmd utility. Wincmd may also be used to
invoke Notepad with the *.prg file filter. An options dialog is available to
change the editor and calendar options. To install, unzip to a temporary
directory, then use program manager to run setup.exe in the usual manner.
After the programs have been copied to the necessary directories, the
temporary directory can be deleted. Registration directions are provided in
the help file, the cost is $20, or $40 if you want the source code. The
program as provided is complete, without nag messages. The initial splash
screen will go away after three seconds, or as soon as you press a key or
click the mouse. Obviously, I would prefer that you register the program, but
if you have any comments, don't hesitate to contact me, even if you haven't
registered.
