sum

1.    In  {domain  theory},  the  sum  A  +  B  of  two  {domain}s
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.    A  {Unix}  utility  to  calculate  a  16-bit  {checksum}  of

differ  on  machines  with  16-bit  and  32-bit  ints.

{Unix  manual  page}:  sum(1).
