-> Renames is used to regroup the elementary items of a group into a new group.
-> Renames should be coded with 66 level number.
-> There should not be any picture class coded for 66 level number.
-> The renames field will be allocated with the same memory space as defined or elementary items of renamed group item.
->66 level number cannot rename another 66 level number or 01 level or 77,88 level numbers.
02 B PIC X(8).
02 C PIC X(2).
03 E PIC X(2).
03 F PIC X(4).
02 G PIC X(5).
02 H PIC X94).
66 I RENAMES C THRU F.
here we are regrouping the elements C,E,F into I.
now the memory allocating for I = C+E+F. that is 2+2+4=8.
