HP11C Calculator
			  ================


RUN IT FROM THE CLI !!!


This is version 1.01 (a few bug fixes & minor changes from the previous
version).

This program emulates an HP11C calculator. Everything is there, including
the program mode (with the instructions displayed as usual, as numbers
...). By default, it's even as slow. It is callable from Workbench or CLI.

Usage
-----
You can pass as argument a program to be loaded (not run): from CLI, type
hp11 <name> (you must be in the directory containing the program, cf
miscellaneous), from the Workbench click on the program's icon, press &
hold shift and double click on the hp11's icon.

Basically, the program opens a window containing an image of an HP11C (it
will only look right if you use the standard workbench colours), it looks
best on an interlaced screen but will work in non-interlaced mode (however,
the image will be rather elongated). You select keys with the mouse or the
keyboard, the following keys are supported: 0..9,.,+,-,*,/,return (for
enter), esc (for ON).

The ON key is treated specially: when you select it, the HP11C becomes an
icon that you can move around with the mouse. To turn the calculator back
on, double-click on the icon.

The following menu options are avalaible:

   Project
      New		Clear HP11 memory (equivalent to ON -)
      Open	  AO	Load an HP11 program
      Save		Save program under current name
      Save As	  AS	Save program under a name
      Print		Print program -- unimplemented
      Quit		End program

   Edit
      Copy	  AC	Copy number in display to clipboard
      Paste	  AP	Enter clipboard as a number into X

   Options
      Radix
	 Point	  A.	Select UK/USA format for numbers
	 Comma	  A,	Select European format for numbers
      Speed
	 Slow		Program's execute at HP11C speed
	 Fast		Program's execute faster ...
      Icons		Save an icon with a program ? Default = Off when
			called from CLI, on from Workbench

For more details (especially concerning HP11C programming), refer to HP's
manual. (I didn't want to get sore fingers ...)


Miscellaneous
-------------
Please send all bug reports, suggestions for enhancements ... to me.

The format for Copy & Paste is not the same (alas ? if you disagree
strongly, please send me a note): Copy essentially places an image of what
is on the display in the clipboard, thus 200*10^23 becomes 200.0000   23.
Paste reads a number in the format +/-x.xE+/-x.

The ARP file requester is used if arp.library is present.

The program must be able to find the file HP11.PIC. It should be in the
same directory as the executable file. However, if you run the program
from the CLI, you must either give an explicit path when you execute the
program (as in df1:hp11/hp11), or have the file hp11.pic in the current
directory. In other words, the program shouldn't be in your PATH
specification (for instance in C:).

This program is placed in the public domain.
