Section 10,11: $

 In a format specification, the dollar sign character ($) modifies
 the carriage control specified by the first character of the
 record.  It only affects the files for which the 'FORTRAN' carriage
 control attribute is in effect.

 On U*X systems, it also affects files if 'LIST' is in effect.

 In an input statement, the $ descriptor is ignored.

 In an output statement, the following rules apply:

    - If the first character of the record is 0, 1, or
      ASCII NUL, the $ descriptor is ignored.

    - If the first character of the record is a space or
      plus sign (+), the $ descriptor suppresses carriage 
      return (after printing the record).

 For terminal I/O, whenever trailing carriage return control is
 suppressed by the $ descriptor, a typed response follows output on
 the same line.
