Parsing text string

I am looking for a function or calculation to determine if a text string contains any alpha characters or is all numeric.

The implementation is for a check number field that will automatically increment by 1 for each new check. If the previous check is an electronic transfer there will be no check number in the field. The result is the next check number is 1. I want to keep the previous numerical check number stored if there is an alpha character in the field.

Try:

not Exact ( text ; Filter ( text ; "0123456789" ) )

Works like a charm. Thank you.
