	ENCOUNTERED.  THEREAFTER, IT WILL ONLY BE REDEFINED, AT THE SAME BLOCK
        LEVEL!! IN OTHER WORDS, SCOPE RULES ARE IGNORED AFTER FIRST APPEARANCE
	OF A MACRO, UNTIL THE BLOCK IN WHICH IT WAS FIRST DECLARED GOES AWAY.
	HOPEFULLY, LATER, A SEPARATE MACRO BLOCK STRUCTURE WILL BE INVENTED.

#KR	DATUM(ITVARR[EXPR],REAL ARRAY)[1] IN A KKP PROGRAM CAUSED A
	BAD STRING TO BE ENTERED FOR THE ARRAY NAME IN THE ARERR UUO

	REPRESENTING THE RESULTANT REAL ARRAY DIDN'T HAVE A LEGITIMATE
	ITEMVAR SEMBLK POINTER IN $VAL, SINCE IT'S SO COMPLICATED.  
	MAYBE IT SHOULD HAVE, BUT FOR THE PRESENT, I'VE INSERTED A
