111 ZIPFS


Filing systems where I don't know the number:

IDEFS ...?
iZIPFS	Argo Zip
ZIPFS	Alsystem's zip
ATAFS ...?

To find out a filing systems number if you have it, select if (eg *RamFS),
then do: SYS "OS_Args",0,0 TO fsnumber%

To convert a filing system number to its name, use:
	SYS "OS_FSControl",33,fsnumber%,buffer,buflen
which returns a null-terminated string in buffer, or "" if not known.

Note: When a DOS disk or partition is opened as an image file, the
returned filing system number is 0.
