[M3devel] [M3commit] CVS Update: cm3

[Jay]

Reading the code ...there is a command line option to the compiler to apparently make it:
               ADR  (x: T)            : UNTRACED REF T. 
Good?bad?better?different?
Seems more type safe.
I haven't tried it.

The following operations are primarily used for address arithmetic:               ADR  (VAR x: Any)            : ADDRESS 

     infix     +    (x: ADDRESS, y:INTEGER) : ADDRESS
     infix     -    (x: ADDRESS, y:INTEGER) : ADDRESS
     infix     -    (x,y: ADDRESS)          : INTEGER
ADR(x) is the address of the variable x. The actual argument must be a designator but need not be writable.
