Read Lines from One file.. and create another.. and

Hello Members,

I have one file which contains million of supplier code. I need to load these codes into database 1000 at a time.
Database procedure reads from an external table which is based on the unix files.

All I want to do is to read from the bigger file e.g. MAIN_FILE.txt and create another files LOAD_FILE.txt (with only first 1000 records). Then run a pl/sql block. Once that is done create new LOAD_FILE.txt file with next set of 1000 records (i.e. from line 1001 - 2000).

But I need to make sure that first 10 lines of the LOAD_FILE.txt always contains a header .. so the 1000 records should be amended from line 11 onwards.

I have the pl/sql bit of code ready in another script (which I will call from this script everytime 1000 lines are created in LOAD_FILE.txt.

Can anyway help?

Thanks
