Let me see if I understand this...

The user would type, for example
	set label gprintf("format",var)
and internally this would be converted into a call to the existing
function of the form
    gprintf( (char *)temp, sizeof(temp),
	(char *)format,
	(double)current_radix,
	(double)var);
followed by copying temp into the appropriate place, in this case
the label structure.

From the user's point of view (and the parser's), gprintf always has
exactly two parameters:  (char *)format and (double)var.

Is that correct?
