DOS allowed up to 30 character filenames with any characters save for the
comma (which was used to delineate parameters) and maybe one or two other
characters I'm forgetting. But even control characters were allowed (and
these were used to "hide" files sometimes or confuse people trying to load
them, since they didn't show up in the catalog).

ProDOS only allowed 15 character filenames, alphanumeric and periods only.
I never used GSOS but I assume it used a similar directory format.
