Veera,
reg level 77 & 01.
This has no diff in MVS COBOL, VS COBOL II.
Inearlier versions of cobol.
if you declare an elimentary data item at level 01
01 ws-rec pic x(01).
01 ws-rec2 pic x(02).
in memory
xyyyyyyyyyyyyyyyyyyyyy (here y is blank nothing is stored in that).
xyyyyyyyyyyyyyyyyyyyyy
where as if its at level 77
77 ws-rec pic x(01)
77 ws-rec 2 pic x(01)
in memory
XX
you can observe that memory is being saved.
however there is no diff in MVS Cobol or VS Cobol II |
