Blank Control (BN, BZ)

After BN is used all embedded and trailing blanks in numerical input fields are treated as nulls, i.e. ignored. After BZ they are treated as zeros. These descriptors have no effect on numerical output. The initial default, which depends on the BLANK= item in the OPEN statement, is restored at the start of every new formatted transfer.
