I generally agree with what you wrote; however, there is not enough
information to get an idea on how the entire process is structured. If the
full code for the relevant portions of the process is posted, we could
probably figure out where the problem is.

I have used cursors in the past to do this type of upgrades but recently I
have replaced this approach with a single multi-table UPDATE statement; the
code is much easier to maintain.

But no, Dennis I can't see that being the problem.  If I understand his
email, the customer order table is the one he's updating and it has 40K
rows.  He is setting a cursor through a smaller table.  If that smaller
table has 1 row it's fast, and gets incrementally slower as he cursors
through each row.  Now yes, the cursor itself takes some time to "open" the
recordset, but his example shows a marked difference between 1 row in the
table and 30 rows.  But the number of rows in customer order table itself
isn't changing.  Again, that's my understanding of the OP

Is the column receipt indexd?

If not, that is the reason for your problem.

The update statement is
Update ctrectyd set canceled = .startdat where receipt eq .vrecnumb

Thanks

I have an issue on timing.  I have two tables, one holds daily transactions
and the second holds customer orders.  
The daily transaction table could hold from 10 to 500 records.  The customer
order table holds approx. 40,000 records.
I am just reading a daily transaction, looking it up by order number and
updating the processed date I the customer 
Order table.    

In testing I found the following results:  If I key an update it is complete
in just a second.  
If the daiily table has 5 records it takes approx. 4 1/2 seconds per record
to process.
5 records take 4.5 seconds per record,
10 records take 8 seconds per record, 
20 records take 15 seconds per record,
30 records take 24 seconds per record.

Why the increment in processing time, any suggestions?

If I key an update
