1 ROLlin
	A Program to do ROLLINS from/to DK, DP or DR to MM or MT tape
 
	Magtapes involved should be mounted as foreign volumns Any format of
	disks can be copied/written since copies are strictly block by block.
 
	Calling proceedure:
 
	MCR>ROL	MT0:xxxxxx=DK2:/sw   xxxxxxx is label for file name on tape
					 currently name must be 6 letters
 
 	Legal devices are	DK0->3	DP0->2	DR0->3	MT0	MM0
 
 	Switches must be at end of command line. Current switches are:
 
 	/VE(rify)	Check tranfer (to disk) by re-reading buffer  back
 			from output volume. (No compare is done.)
 
 	/OV(erwrite)	Overwrite  any data  on  output tape, (i.e. do not
 			follow normal  proceedure of searching  for end of
 			volume before starting write.) Used to write first
 			save  set on  a tape.  Also  done automatically if
 			copying a large disk to the streamer tape MM.
