Probably more like 5 or 6 months since the last one of these...

This video is switching from the one-long-string based "filetable" to a 'more robust' implementation with 16 byte (1 word) entries per file/pgm. I then proceed to try and fail and try and eventually print out the new version of the file table under the menu F) command.

- This video may be a bit jumpy due to lazy editing style and cutting out long pauses, repetitions, and ramblings, but it does more closely follow my normal thought processes (fragmented and disorderly).
