FROZVAL This function (and its UPDATER) access the arguments frozen
into function closures.  It takes two arguments - a number specifying
which frozen argument (numbering from the left) is to be accessed and
the function closure.  Try the following:
.tp12
 	: FUNCTION ADD3(X,Y,Z); X + Y + Z END;
 	: VARS ADD; ADD3(%5,6%) -> ADD;
 	: ADD3(4,5,6) =>
 	: ADD(4) =>
 	: FROZVAL(1,ADD), FROZVAL(2,ADD) =>
 	: 10 -> FROZVAL(1,ADD);
 	: ADD(4) =>
 	: [PURPLE] <> FROZVAL(1,ISCOLOUR) -> FROZVAL(1,ISCOLOUR);
