I Editing
The I edit descriptor transfers decimal integer values. It takes the following form:
Iw[.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 must be of type integer; logical and real items are also allowed if the compiler option check format is not specified.
The G edit descriptor can be used to edit integer data; it follows the same rules as Iw.
Rules for Input Processing
On input, the I data edit descriptor transfers w characters from an external field and assigns their integer value to the corresponding I/O list item. The external field data must be an integer constant. w must not be zero.
If the value exceeds the range of the corresponding input list item, an error occurs.
The following shows input using the I edit descriptor (the symbol ^ represents a nonprinting blank character):

Rules for Output Processing
On output, the I data edit descriptor transfers the 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 a sign (a plus sign is optional for positive values, a minus sign is required for negative values), followed by an unsigned integer constant with no leading zeros.
If m is specified, the unsigned integer constant will have at least m digits, padded with leading zeros if necessary.
If the output list item has the value zero, and m is zero, the external field is filled with blanks; if w is also zero, the external field is one blank.
If w is zero, the external field has the minimum number of characters necessary to represent the value, left justifying the value with no leading blanks. If both w and m are zero and the internal value is zero, the external field is one blank.
The following shows output using the I edit descriptor (the symbol ^ represents a nonprinting blank character):
