How to Loop through all records on a Tabular form

Hi,

Can you please let me know, how to loop through all the records in a block.

The records are in tabular form and Block is not a database block.   I Just want to use some procedure or package to loop through all the records and insert into some  temporary table in database.

If any one has the same scenario, please give me the logic to do this.

Thanks in Advance,

Anil
