Document DE 5 is running along smoothly; I sat bashing my head into the italics algorithm for two hours before I discovered that changing a sra a to rr a and removing another would fix it. Argh... But now bold, italic, and underline seem to work perfectly in display, and they can be set during realtime typing. Backspace kinda works; all of the routines are there, and they don't crash. However, although the previous letter partially clears, in memory the character remains for some reason. Also, backspacing or editing a file after closing it and opening it again seems to create a weird overwrite bug that I need to work on.
Hopefully the most major hurdles have been cleared by now, and the majority of the coding that I still need to do involves tedious line break, scrolling, and other routines that have to be exactly right to prevent a crash. I also am going to need a computer program that can convert .83p Document DE files in .txt or .rtf, so if anyone would be willing to do this, please contact me. As my Calculus teacher says, onward and upward!
