Hi,


Level 77 can be used to describe independent elementary items in the Working-Storage or Linkage Sections.

Level 01 can be used to describe both elementary and group items. Any item described in Level 01, the system is putting on Double-Word boundary and inserts slack bytes if necessary.


Hope this helps.

Cheers
Ashwin

Level number 77 is used only to declare independent elements.

Whereas in the case of Level number 1, it can be used as an independent element or a group item.

Generally if the independent element is to be declared we use Level number 77.
