- RPNCalc for the Series 5 (SHAREWARE)
- --------------------------------------
-
- Disclaimer
- ----------
- This version of RPNCalc is version 1.48
- Use this software at your own risk. I accept no responsibility
- for loss of data.
-
- History
- -------
-
- Version 1.48 Released 2/2/99
-
- Fixed bugs with the Int and h.mmss functions when using a comma as a decimal point
- (rather than a dot).
- Adjusted the stack handling with dual-operand logical operations (such as OR and AND)
- to consume the stack, as per HP calculators.
- Reversed the h.mmss and Inverse h.mmss functions to match HP calculators - h.mmss now
- calculates decimal hours to hours-minutes-seconds.
-
- Version 1.47 Released 4/10/98
-
- Fixed a nasty bug introduced in version 1.45, where RPNcalc loops on overflow
- errors, eating up all your memory until it crashes out!
-
- Version 1.46 Released 16/9/98
-
- The primary financial functions (PMT, PV, FV, TERM and RATE) have been rewritten. You
- can now solve for any one unknown, given any of the other four (eg it now takes
- account of FV when calculating PMT, which previously it did not). Also, calculations
- can now be made for payments at the beginning of a period as well as the end.
- Optional thousands separator implemented (eg 100,000 displayed rather than 100000).
-
- Version 1.45 Released 10/8/98
-
- Keyboard handler rewritten (as evidenced by the keys appearing to stay pressed
- for as long as they are held down by the screen pointer). Now hopefully
- Geofox compliant.
-
- Version 1.44 Released 27/7/98
-
- Improved the stack-handling to exactly replicate Hewlett-Packard. Now when
- stack lift is enabled, entering ANY VALUE will lift the stack, except for the
- two cases of ENTER and CLRX. Thanks to Rene Gysel for pointing this out.
- All the app and opo files merged into one app file.
-
- Version 1.43 Released 25/5/98
-
- Added 3 shortcuts at the request of Tadashi Homma as follows: "m" = +/-;
- "z" = square root and "x" = 1/x. Key help indicates which keys have shortcuts.
- The "z" and "x" match the HP-200LX, and "m" matches the built-in calculator.
- Corrected a flaw with the stack-handling of X^Y to Y^X. These are dual-operand
- instructions, so should cause the stack to drop, but did not.
- Thanks to Dieter Tackmann for pointing this out.
-
- Version 1.42 Released 21/4/98
-
- Maximum formula length increased from 60 characters to 250.
- Thanks to Tim Wortley for this suggestion.
-
- Version 1.41 Released 12/3/98
-
- Floating to IEEE hex function added.
- Engineering display mode added - requested by Roland Heuberger.
- Changed X^Y to Y^X - this matches HP calculators and is more intuitive - thanks
- to Marcus Herold for pointing this out.
- Fixed MODULUS flaw. eg 70.9 INV INT displays 0.90000000000000006 not 0.9 - this
- is acually the value returned by EPOC32. I now calculate the MODULUS (fractional
- part) myself. Thanks again to Marcus Herold for telling me about this.
- Changed the key logos for square root, cube root and XrootY. X^-2 is not actually
- the square root of X, but the reciprocal of it! Thanks to Pappas Sotirios for this
- one.
- Fixed an error that occurred when setting up key constants - press SET button
- - "Set constants keys" - "Set c1 key" - "Select from list 1" - press the "Lists"
- button - gives "Subscript or dimension error". I must have broken this in release
- 1.4. Thanks to Anders Nilsson for noticing this. I am amazed it took two months
- to be spotted!
-
- Version 1.4 Released 7/1/98
-
- Rectangular-Polar conversion added.
- Decimal hours to hours-mins-secs added, allowing time calculations.
- Random number function.
- 32-bit binary to IEEE floating or DEC VAX F_Float.
- Twice as many user-definable Constant/Conversion/Formulae keys.
- Cosmetic revamp.
-
- Version 1.3 Released 26/12/97
-
- The calculator can be "flipped" from left-handed to right-handed
- (registered users only).
- The "inv" key can be locked.
- No longer a file-based app (and never should have been!).
- Includes a utility to display all ascii codes in the selected number base
- (removing the need to also have my Ascii program).
- The unregistered restriction that displayed certain functions in an informational
- message has been removed. I now feel that there are sufficient benefits obtained
- from registering the program, that this restriction is unecessary.
-
- Version 1.2 Released 7/12/97
-
- Fixed stats update bug (X-register was sometimes ignored)
- Fixed clock bug - clock now obeys the system setting.
- Changed numeric keypad layout due to the requests from users.
- Moved the hexadecimal keys to the left and ordered the keys 1,2,3 etc
- to be more like a standard numeric keyboard.
- Added a feature that lets RPNCalc take over the silkscreen Calc key.
-
- Version 1.1 beta Released 27/10/97
-
- Many improvements: 4 user defined formulae instead of 2, user-definable labels
- for the constants, conversions and formulae keys, INT, MOD and % functions,
- MAX and MIN statistical functions, financial functions, context help for every
- key, much more usable statistical facilities with the ability to view, delete
- and modify the stats values, etc.
-
- Version 1.04 Released 16/10/97
-
- Fixed bug due to users setting International-Number decimal-point
- to the "comma" character. This prevented registration. Revamped display
- to create space for financial-functions. I have released this version prior
- to implementation of these functions because of the bug fix.
-
- Version 1.03 Released 10/10/97
-
- Solved the missing "send to background" message when going to another
- program from the System Task List.
-
- Version 1.02 Released 9/10/97
-
- Moved stats counter out of M9. Stats count now on key
-
- Version 1.01 Released 9/10/97
-
- Fixed RAD50 bug - shouldn't be allowed in signed mode
- Added Hotkey and Escape to background
-
- Version 1.0 beta Released 7/10/97
-
-
- Installing RPNCalc
- ------------------
- 1. Make sure you have access to the System directory. For this, goto the preferences
- in the system screen. Check the 'Show 'System' folder' option.
-
- 2. Got the System\Apps directory and create a new directory called 'RPNCalc'.
-
- 3. Switch to this directory and copy all the supplied files to this directory (excluding
- this file). Ensure that NO conversions are done when copying any of the files.
-
- 4. The program should now appear on the Extras bar.
-
- 5. If upgrading, delete ALL THE OLD FILES and replace with the new (registered users
- will want to keep their existing RPNCalc.ini file).
-
- Read the supplied help file, which is accessible from the program.
-
- Registering
- -----------
- RPNCalc is shareware. If you like it and wish to continue to use it you should
- register it. You may freely distribute RPNCalc as long as all files in the package are
- included.
-
- Registering bring a number of benefits. See the help file for details.
-
- Registering (cash preferred) costs รบ10 UK, $16 US or the equivalent in other foreign
- currencies plus 10%.
