Consider the following high level programming segment. Give the contents of the memory locations for variables $W, X, Y$ and $Z$ after the execution of the program segment. The values of the variables $A$ and $B$ are $5CH$ and $92H$, respectively. Also indicate error conditions if any.
var
A, B, W, X, Y :unsigned byte;
Z :unsigned integer, (each integer is represented by two bytes)
begin
X :=A+B
Y :=abs(A-B);
W :=A-B
Z :=A*B
end;
