Hmm. Linked lists. That brings back memories: half a lifetime ago, as a
University student, I did a Directed Study, in which I wrote a text
editor for TRS-80s, effectively reverse-engineering the Context Editor
that was supplied with the McGill University MUSIC operating system for
S/370 and compatibles. (I'd come to know and love that editor from two
years of high school programming on a MUSIC timeshare system; that's how
I managed to get into Midrange programming already knowing EBCDIC.)
My text editor used almost the entire second floppy drive to store the
lines of text, as full-sector records, and used an in-memory
doubly-linked list to sequence them. And it was implemented in TRS-80
Mod I Disk BASIC. I suspect that anything that can be implemented on
that platform can be implemented on ANY platform.
Got an A in the Directed Study. Then wrote the manual for it, the
following semester, when I took tech writing.
Happy New Year (or as Sandra Boynton might say, "Hippo Gnu Deer").
