Edit descriptors
Chapter 9 263
negative values are output in twos complement form, their high-order bits are nonzero and
cause the field to be filled with asterisks when w is less than the number of hexadecimal digits
in the entire output value. If m is set to 0, a zero value is output as all blanks.
The field width required to fully represent the hexadecimal value of an item is twice its size in
bytes. For example, a CHARACTER*12 item would require a field width of 24 characters.
Table 9-24 provides examples of the hexadecimal edit descriptor on output.
