w: specifies the field width of the input value, in bytes.
d: specifies a divisor for the input value. If the informat includes a d value, the input value is divided by 10^d.

Details

The ZDB informat reads zoned decimal data that are produced in IBM 1410, 1401, and 1620 form, in which zeros are left blank rather than being written. Each digit is represented as an EBCDIC character as previously described for the ZD informat. The only differences are the way in which zeros are represented, and that the ZDB informat does not allow you to use a d value while ZD does. The ZDB informat treats EBCDIC blanks ('40'x) as zeros. (EBCDIC zeros are also read as zeros.) Like the ZD informat, the ZDB informat also uses the rightmost byte to represent both the least significant digit and the sign.

The table under ZD shows the convention that is used to store digits in zoned decimal format. The following table shows several examples of how the ZDB informat reads data.
