[Coco] Valid file names for Disk BASIC

[L. Curtis Boyle]

Yes, although I am not aware of any restriction on using the digit ‘0’ - I have used them just fine.
(You can even use high bit graphics characters to make a DIR display little pictures - a trick that also works on Level II OS-9 to make colors, etc.). Although, that makes files much harder to load.

The information makes mention that a slash, a colon, a dot and the digit zero are not permitted in the file name. It makes no mention of any other characters, such as dashes, underscores, dollar signs, and so on.
