Editing Numeric Data
The Z Descriptor
The Z w and Z w. m descriptors convert a data value to a hexadecimal (base sixteen)
external representation. You can also produce hexadecimal conversion using an I w.
m.16 descriptor. The hexadecimal digits are 0 through 9 and uppercase letters A
through F. Each hexadecimal digit represents four bits of the internal data value. On
input, the lowercase letters a through f are equivalent to the corresponding uppercase
letters.
For example, suppose the data item is type INTEGER*4. The hexadecimal
conversions produced are shown in Table 7-5 (circumflexes designate blank
characters).
