Cursors Processing

When I was inside a cursor loop I am updating records but not commiting records.

Cursor ....
LOOP

Updating each record balance amount

End Loop
Commit;

Some times I need to process each record balance two or three times. Does it cosider the balance amount before entering cursor loop or updated balance amount?

As you are commiting outside the loop it will consider the old value only.

Cusor takes values from the result set. Does a Cursor not Update the values in the result set? Which area does it use to store updated value? If it use the result set it should return updated values only.
