-- Abstract     :  This generic package allows the user to
----------------:  input data types from the keyboard
----------------:  while checking the input for errors. (Proper
----------------:  Type:  syntax and ranges.)
----------------:  A procedure for checking input of characters
----------------:  for a proper subrange of the character set is
----------------:  provided.
----------------:  When an error is encountered, an error message
----------------:  is displayed and the user is allowed to reenter.
----------------:  Output routines are provided to allow the user
----------------:  to do I/O with only one instantiation.  Screen
----------------:  manipulation (i.e. NEW_LINE) should be done with
----------------:  TEXT_IO directly.
----------------:  Instantiations require a FIELD_WIDTH which
----------------:  specifies the maximum field width for the input
----------------:  of the corresponding type.
