syntax for using a variable in an array

[Richard Kreiss]

Top post:

Not your question. But if you are looking for missing invoice numbers why not do the lookup based on an index of invoice numbers.?

Get the first invoice # into a dummy field, add one and a getnext. If it matched repeat until it doesn't, post to your array. Add one and compare again, no match, post to next array element. Repeat until the variable matched the invoice number. The do a getnext. And repeat

What is inv(2) defined as?
