Copybook structure using FILA

This tip is helpful for beginners, everyone else might know it :)

When we create a copybook in cobol, we have the PIC clauses for declaring the variables. Hence the starting position of each variable is difficult to find out.

For this, we can view the copybook using FILE AID option 8 - which gives the detailed structure of the copybook like starting position, ending position, length and type of field.
