window7.c
/*
A true attempt at making a window program.
Seriously. Yes.
By Andy Collins
Debug help from Jon Blocksom.
First verion does seem to work.
Second version. Add an array of Window.
Third Version. Work on pointer problems.
Fourth Version. Jon fixed the problem. Now add a Window Stack.
Fifth Version. Fixed probs with stack and am now changing prog purpose.
Recreate the 'SunView' system of windowing. Difficult, but hah!
Sixth Version. Resizing Windows is the first step to this. Also start using
the mouse as input device.

Set of C programs found on old 5.25 floppy disks from when I was a nerd at Thomas Jefferson High School for Science and Technology in the computer systems lab between 1988 and 1992.

It is a simple "windowing system."

https://gist.github.com/1561312#file_windowtest.c

It is worthy of note that Jon Blocksom helped debug a pointer problem.

http://twitter.com/jblocksom

See
https://gist.github.com/1561312#file_window4.c
https://gist.github.com/1561312#file_window5.c
https://gist.github.com/1561312#file_window6.c
https://gist.github.com/1561312#file_window7.c

Anyone can do whatever they'd like to with them--if anything.

I remain a nerd.
