Notes

On RISC OS and Arthur OSWORD &14,0 calls SWI NetFS_DoFSOp, but if you call NetFS_DoFSOp directly the control block is passed and returned differently.

 OSWORD &14,0:
        XY+00 01 02 03 04 05 06 07 08 09...
 Send:    |00|sz|00|fn|00|00|00|command data...
 Receive: |  |sz|ok|er|returned data...
 
 NetFS_DoFSOp:
        R0=function
        R1+00 01 02 03 04 05 06 07 08 09...
 Send:    |command data...
 Receive: |returned data...
        R0=0 if ok or R0=>returned error block
