This is to "83.67.106.202" (!) -- you say that "|" is not allowed in filenames because it is a shell escape. Please provide an example? (Or anyone who is reading this). MOS 3 allows you to construct control characters like |S for ctrl-S, but when the DFS came out, we were not at MOS 3 yet and this was not a feature that existed. So what did | do at the time?

SAVE "FO|O"
with a 'Bad name' error, but SAVE "FO||O"
results in a file named FO|O
, which can be loaded back with LOAD "FO||O"
. You can also do SAVE "||||||||||||||"
as the resulting filename has only seven characters. In practice, only printable characters appeared in file names, though a lot of PD discs used Teletext characters in their titles. (FWIW | has another unrelated function of starting comments, e.g. *| This is a comment.
