    	    +TYO GIVEN AN UNBOUND VARIABLE AS THE FILE TO OUTPUT
    	    TO, RANDOMLY BASHES LISP, STARTING ROUGHLY IN THE AREA OF UNBND2.  IT SEEMS WORTH
    	    THE COST OF A CHECK
    	--------
    	The only bug that I could find with regards to +TYO was that when you gave
    	it a T, the check succeded, but it used ttsar+truth rather than the
    	file-array in TYO.  This has been fixed.  Otherwise, when *RSET is on the
    	second argument is checked -- it must be an ascii, output file array.

    My apologies; it wasn't anything to do with +TYO.  The bug was in the form
    (PRINC '|FOO| OUTPUT-FILE) which compiles into a STRT UUO.  If OUTPUT-FILE
    is unbound, this bashes low core.
--------
A check has been put in STRT for this condition.
