HI.....
As it was said in the above answer....if you specify
occurs 0 clause, the system allocates 8KB pages of memory
at a time.However ,there are no advantages to using this
occurs 0 other than the fact it is only easier to code
occurs 0 than it is to estimate the size of the internal
table.

but there is a disadvantage of using this,
dont use occurs 0 if you expect to store less than 8KB in
an internal table.if you do, the system will allocate 8 KB
from the paging area.Memoory will be wasted and paging
could increase, resulting poorer performance.
(for more details refer "sams ABAP/4 in 21 days" page no

hope it helps u.....
