Answer / rkt
Level number is used for Elementory data items or group
items which hold some values to rapidly change in program.
but 77 level is used for declaring constant or fixed
elementory values which are not to change during the
program execution .

Answer / mchava
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
