  13:  * returns -1 to indicate failure to complete a date (i.e., a return alone
  14:  * was entered on a line).  If the date is invalid, it must be retyped.
  15:  * I know it is unfortunate that we can't have a plato arrow type judging
  16:  * system here.  I just don't want to go to all the hassle of making one now.
  17:  * perhaps this is an area of improvement for this program.  RK  11/10/80.
