Intel® Fortran Compiler 16.0 User and Reference Guide
The Z data edit descriptor transfers hexadecimal (base 16) values. It takes the following form:
Zw[.m]
The value of m (the minimum number of digits in the constant) must not exceed the value of w (the field width), unless w is zero. The m has no effect on input, only output.
The specified I/O list item can be of type integer, real, or logical.
On input, the Z data edit descriptor transfers w characters from an external field and assigns their hexadecimal value to the corresponding I/O list item. The external field must contain only hexadecimal digits (0 though 9 and A (a) through F(f)) or blanks. w must not be zero.
If w is zero, the external field has the minimum number of characters necessary to represent the value. If both w and m are zero and the internal value is zero, the external field is one blank.
If the value exceeds the range of the corresponding input list item, an error occurs.
The following shows input using the Z edit descriptor:
Format Input Value
Z3 A94 A94
Z5 A23DEF A23DE
Z5 95.AF2 An error; the decimal point is invalid
Z0 42 2A
On output, the Z data edit descriptor transfers the hexadecimal value of the corresponding I/O list item, right-justified, to an external field that is w characters long.
The field consists of zero or more blanks, followed by an unsigned integer constant (consisting of hexadecimal digits) with no leading zeros. A negative value is transferred in internal form without a leading minus sign.
If m is specified, the unsigned integer constant must have at least m digits. If necessary, it is padded with leading zeros.
If m is zero, and the output list item has the value zero, the external field is filled with blanks.
The following shows output using the Z edit descriptor (the symbol ^ represents a nonprinting blank character):
