	Description:
	-----------
		This command performs a restore from streamer tape in the same manner
		as the QICKREST tool. The only difference is, that no streaming mode
		is applied, i.e. that the disk blocks are read from tape block-by-block.
		
		TOANDFRO should be used only in special service cases:
		If a backup set is not restorable in the normal way (RESTSTR, RFILRESTR,
		QICKREST) because an irrecoverable read error stops the streaming mode,
		tools like BUSCHA, however, succeed to read the tape upto the end, there
		may be a chance, that the data are not lost (especially, if the backup
		set is the only one and contains valuable data). In those cases reading
		the streamer tape in start-stop-mode with retries on defective blocks
		may be successful.

		As this is not the natural way of handling the streamer tape device,
		there is the disadvantage, that about 1 hour is needed to restore 10M.

		Note:	Neither the   directory size 
			nor the       disk capacity    must be changed!
