Entry of year:

This field will accept only the numbers 1987 thru 2050.
If the field is preloaded with a year there are
    2 special characters which can be used:

    +  will cause the displayed year to be incremented by one
    -  will cause the displayed year to be decremented by one

If either of the above characters is entered, the field will be
    updated as specified and no further entries will be allowed.

For ease of use:  If any character is typed in the first position
                  of this field, the remainder of the field will
                  be blanked out.
                  If you desire to modify other digits, use
                  the right-arrow key to step up to them.
