Sorry

SELECT max(BILLNO) FROM dbf(1) INTO array laDummy 
THISFORM.TEXT1.VALUE = laDummy + 1 && same as laDummy(1)+1

By the way, I suggest you NEVER specify a work area, like "USE yourtable IN 5". A better solution is

USE yourtable ORDER yourtag IN O ALIAS somemeaningfulalias AGAIN

It is a much better approach. In stead of SELECT 5 you write SELECT somemeaningfulalias. Much more flexible, and also much more readable. I guess you will agree that it is easier to remember SELECT invoicecustomer than SELECT 5.
