Section 10,13: A

 A[w] (Character Editing)

 If the corresponding I/O list element has a character data type,
 character data is transmitted.  If it has any other data type,
 Hollerith data is transmitted.  The value of "w" must be less than
 or equal to 2**31-1.

 On input, transfers "w" characters or Hollerith values from the
 external record and assigns them to the corresponding list element.
 If the input value contains fewer characters than "w", it is padded
 on the right with blanks.  If the input value contains excessive
 characters, it is truncated on the left.

 If the variable is numeric, the ASCII value of each character is
 placed in each byte of the variable, starting at the low-order
 byte.

 On output, transfers the contents of the corresponding I/O list
 element to an external field "w" characters long.  If the output
 value contains fewer characters than "w", it is padded on the left
 with blanks.  If the output value contains excess characters, it is
 truncated on the right (for numbers, the high-order bytes are
 lost).

 If the output value is numeric or untyped, the ASCII value of each
 byte of the variable, starting at the low-order byte, is
 transferred to the record.

 The "w" can be omitted and defaults to the number of characters in
 the character variable or the number of bytes in the numeric
 variable.
