CRYPTNOTRUNC, Not positioned at file start or EOF. TRUNCATE disallowed on the encrypted file ffff
Run Time Error: An OPEN or USE command specifies a TRUNCATE deviceparameter on a encryption-enabled device which is not positioned at the end of a file.
Action: When using encryption, because encryption algorithms maintain state as they process text, a TRUNCATE is only permitted at the beginning or end of a file, the former deleting the entire contents, and the latter effectively a no-op.
