Answer / cauvitha
comp - used for binary representation. To make the calculations faster. it can have S and 9.
Memory usage is
s9(1)-s9(4) - 2bytes
s9(5)-s9(9) - 4bytes
s9(10)-s9(18) - 8bytes
===
comp-3 - used to store packed decimal values. Stores comparitively more values than comp. It can have S, 9, V.
Memory usage is
n/2 + 1 (Even)
n+1/2 (odd)
