Variable grouping
structures
1.- ORDERLY ASSEMBLY OF VARIABLES
(ARRAYS)
Arrays or arranged data sets (arrays) collect variables of the
SAME type, saving them sequentially in memory. The
maximum number of variables they can hold is limited only
by the amount of available memory. The type of variables
involved can be any of those already seen, with the only
restriction that all the components of an array must be of
the same type.
