very old basic code


Well, these are some programs I made from 1994 to 1995 or so, in qbasic while I was at school, during my first contact with coding and graphics. Perhapse somebody can use them as a very (q)basic examples of (how not to do) programing, cause most of these applications still run even in Windows XP if you have a copy of qbasic.exe.




QBasic, done in 1994. It calculates the number primes for a specified interval. Of course, no clever algorithm was used; just brute force instead. I had enought fun learning to fake shadows on text mode, so I was not interested at all on the primer calulation algorithm.

Simon game, made in QBasic in 1994. One of my first programming with real graphics. You cannot really play with it nowadays even if it works on Windows 2000, just beacuse the timing was made for a 386... You have the code, so you can try to fix it :)

First attempt to do a user-oriented application. It was a drawing program using ASCII characters. Quite nice, it was able to correctly choose the best text character depending on the tryectory of the pointer. Lot of menus to copy and paste blocks of graphics, and menus to select colors, save to disk and so on.

My most complex creation at that time (1995). Done in Qbasic, made to mimic the PBrush of Windows 95 beta version. A complex logic for the user interface. My first graphics algorithms to draw stars and polygons, and also my first realtime effect for the screensaver of the applicacion.
