 My knowledge of assembler is nil, and I would think that these would be
 assembler for speed.  But I'll cheer like all get out if some other
 reader of the board contributes them.  (In fact, Miller's approach of
 having a complete set of integer operators that run off a precision set
 by the user (programmer) is very attractive:  you enter something like 4
 EQU PRECISION and from then on these operators use four bytes of
 precision; 8 EQU PRECISION gives 8 bytes, and so on.  So the usual
 (16-bit) operators are equivalent to 2 EQU PRECISION using the new
 operators.  As I recall, the set included +  -  *  /   /MOD  */  */MOD
 Just about all one could want.  Current double precision operators in
 the LMI set are, I think, only + and -  (that is, "native" double
 precision:  operands and result all double-precision).  If * and / are
 added, MOD and /MOD should be as well.  (Presumably /MOD would be the
 primitive with MOD and /  defined as that plus a DROP or NIP
 respectively.
