Johnson/!Converter/Docs/History

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

HISTORY
=======

This file contains a brief history of the Converter+ software. As always, it
starts with the most recent (v1.43). A release is indicated by *.

vsn1.43* - Changed the code so that the answer is to 4 decimal places and fixed
           a small pain in the main code (quit when the main window is closed).
           Corrected bug for values of 0. Released to AU and the website

vsn 1.42 - Altered the quit window. It now looks less cramped.

vsn 1.41 - Added a nice little opening screen and played with the help system

vsn1.40* - Revamped the help system so that it no longer needs a text
           editor to be able to read the help files. Fixed a couple of
           pain bugs and rejigged the Info window. Also jiggled with the
           code so that the units showed up (easier than on the top line!)
           Shaved 4k from the wimpslot, altered the code slightly and faffed
           around a bit until I liked it!. Released to AU and the website

vsn1.39-5- Problems with the help system window. It's very annoying

vsn 1.34 - Thought I had it cracked, until I discovered that some of the
           conversions were not as they should be!

vsn1.31-3- Started looking at the help system, mostly, the new versions
           were just big fixes of the other versions.

vsn1.30* - Slight bug fix which I was told about, but I didn't know about.

vsn1.29* - As far as I'm concerned, unless I decide to add
           any more conversions, this program is done and dusted. Of
           course,  it is up to you to ask for more to be added. (Ho hum!) 

vsn 1.28 - Discovered that the temperature converter was goosed!. Whoops

vsn 1.27 - Major problems with the help menu. I discovered that if I took
           out some of the extraneous code, then I could get it to work.  

vsn 1.26 - Discovered that half of the conversions were wrong! and worse,
           some of them didn't work as they should. This was supposed to
           be the final version!.

vsn 1.25 - Help menu added and tested. Not generally released, but was
           tested by a few people (briefly!)

vsn1.24* - Fixed the quit window problem. Thanks should be given to Dave
           Jackson at Clares for helping me with this one. This version
           was sent to AU and the independant WB site (www.treknet.is/WB)

vsn 1.23 - Not satisfied with some of the window handles. Altered them, compiled
           it only to find I liked it the first way!

vsn 1.22 - Added another 14 converters, altered the menus, played with
           the sprites so they looked a bit nicer. The whole addition took a
           further 15 minutes. That's 50 minutes for all the windows,
           menus, debugging, extra code - try doing that under the normal
           BasicVI!.  Buy WIMPBasic now! Main About window played with.

vsn 1.21 - The About window has been altered as has the icon menu and the
           converter menus. The main converter code has been rejigged so that it
           runs a bit more efficiently.

vsn 1.20 - The main window was jiggled for asthetic purposes. The sprites were
           recoded.

vsn 1.19 - The Quit routine was altered so it would work!

vsn 1.18 - The Quit routine was played with - rather unstable, but works

vsn 1.17 - Tracer removed from the main window

vsn 1.16 - Main converter code altered for null entries

vsn 1.15 - Main window was debugged (the "Converter" was deemed clickable)

vsn 1.14 - A double variable was introduced so the program couldn't be fooled

vsn 1.13 - Tracer window added to the main window, there was something "odd"
           going on in the program, and I didn't quite know what, well I did
           the program would convert correctly the first time, but then not
           after that!

vsn 1.12 - The main Quit window was put in. It worked, but not very well.

vsn 1.11 - Didn't happen.

vsn 1.10 - The window frame titles were added so that I could see what I was
           doing. The conversion didn't make sense otherwise!

vsn 1.09 - Main converter code re-written so that it would work better!

vsn 1.08 - Didn't happen.

vsn 1.07 - see above!

vsn 1.06 - Main window adjusted so that it looked nicer. (Pretty colours!)

vsn 1.05 - Bugged to hell. Discovered a rather neat trick though, it is known
           as programming in non-spaghetti style!. Major re-write of all code

vsn 1.04 - beta test version. Didn't like it much. I could enter 16oz to go to
           pounds and it would come back with 1.42!

vsn 1.03 - Didn't happen

vsn 1.02 - Very archaic version of the program. It needed a wimpslot of about
           132k. Vsn 1.15+ uses just 32k wimpslot - though it really can get
           away with one just 20K big.

vsn 1.01 - Really just version 1.00b, but with a different number and a few less
           bugs.

vsn 1.00 - The original version. This took about 20 minutes to code. So that's
           0.21 extra versions in about 15 minutes. C programmers, eat your
           hearts out!

vsn 0.9  - Final BASIC version written. It was to be my final attempt at
           programming under the RiscOS OS. The only big advantage over
           future versions was that it was OS2 compatable. It was never
           released, though did contain all that is in vsn 1.28.

It is worth saying that without WimpBasic, this would never have happened and
what's more, the entire program (including these files, sprites and coding has
taken me less than 1 hour 15!). Under normal circumstances, the addition of
extra code would have made the package more of a swine, but under WB, it's as
easy as falling asleep to a junior Doctor :-)
