sum

   1. <theory> In {domain theory}, the sum A + B of two {domains}
   contains all elements of both domains, modified to indicate
   which part of the union they come from, plus a new {bottom}
   element.  There are two constructor functions associated with
   the sum:

   	inA : A -> A+B       inB : B -> A+B
   	inA(a) = (0,a)	     inB(b) = (1,b)

   and a disassembly operation:

   	case d of {isA(x) -> E1; isB(x) -> E2}

   This can be generalised to arbitrary numbers of domains.

   See also {smash sum}, {disjoint union}.

   2. <tool> A {Unix} utility to calculate a 16-bit {checksum} of
   the data in a file.  It also displays the size of the file,
   either in {kilobytes} or in 512-byte blocks.  The checksum may
   differ on machines with 16-bit and 32-bit ints.

   {Unix manual page}: sum(1).
