LOGCOPY is Acorn's directory tree logical file copier between ADFS and Econet. It needs some minor modifications, very few in fact, to be altered to run with the Videodisc Filing System instead of ADFS.

The changes in lines 1000 and 2240 relate to the way filing system changes are made. Instead of using the usual * commands, ie. *ADFS and *NET, Logcopy changes filing systems by use of OSBYTE 143 with the appropriate internal filing system number. 8 is the number for ADFS and 10 for VFS, so I have replaced 8 in these lines with 10.

Line 1010 detects whether a floppy disc or Winchester disc is being used by using the ADFS OSWORD &70 call. Here I have substituted the equivalent VFS call, OSWORD &60.
