   Once again curiosity strikes.  Anyone know what the files=, conv=block,
   or conv=unblock options are?

Assuming they're the same in System V as they are on SunOS 4.0, the
Sun manual has this to say about them:

     files=n	    Copy n input files before terminating  (makes
		    sense only when input is a magtape or similar
		    device).

	  block	    Convert  variable  length  records	to  fixed
		    length.
	  unblock   Convert  fixed  length  records  to	 variable
		    length.

     The block and unblock options cannot be  combined	with  the
     ascii,  ebcdic or ibm.  Invalid combinations silently ignore
     all but the last mutually-exclusive keyword.
