[AccessD] pls advise: Performance problem => Staging + UpdateBatch?

Hi group,
 
I've got a A2K (that needs to migrate to XP) app that needs to import a flatfile.
A 267kb file takes about 25-28 HOURS(!!) to proces. Yes, it's a slow network.
I need to improve this.
This is how it 'works' now:
1 - read the file on the network to determine the number of lines
2 - start a for x=0 to NumberOfLines loop
3 - check the first x characters in the line
4 - create a new record in a table (table depends on step 3, there are 5 different tables to store the records)
5 - execute an update
6 - goto the next record
 
Here's how I want to do it:
1 - copy the file from the network to the desktop
2 - import the complete file in a staging table
3 - Use an UpdateBatch mechanisme to update the BE.
 
Question:
How can i implement this UpdateBatch? I mean I have to store the records for each table 
and after the complete file is processed I want to update all tables.
 
Question:
I need to implement a transaction. If the processing failes somewhere I need to rollback the changes (if I use an updatebatch this is probably not necesseray but it's good programming I think)
 
any tips/advice is greatly appreciated!!
 
Regards,
 
Sander
