Hi Brahmananreddy,

| What are the differences between 77 and 01 level numbers? |
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.
More points on 01 and 77 level numbers.
01 level
May be used to describe a single field or the start of a group of fields. Level 01 is the only level number that may be used to either begin a group or describe an independent field.
77 level
Reserved for individual elementary items that are not part of a group. In practice, a level 77 item is the same as a level 01 that describes an elementary item.
Hope this helps. |
