The Z Edit Descriptor

The Z edit descriptor is used to display or interpret data values in hexadecimal

(base 16) integer form.

The Z edit descriptor has the following forms:

w OR Zw.m

w an unsigned integer constant that defines the total field width and cannot

exceed 255. The field processed is the

w characters starting at the current

position. After the field is processed, the current position is advanced by

characters.

m an unsigned integer constant that defines the number of digits that must be

present on output.

The Z edit descriptor is used in the same manner as the I edit descriptor where the

number base (

b) is 16, except that the Z edit descriptor always treats the internal data

value as unsigned. (Refer to the description of the I edit descriptor, earlier in this

appendix.) For example, if the data item is an INT(16) in TAL, the following

conversions take place:

The “|” character is used to denote the boundaries of the output field.
