N3SCE – Year Matching

The N3SCE method compares two years. The input field is expected to only contain a year in the form YY or CCYY. The routine ignores the

REFxx

options as there is not enough structure to support them.

Of the local options it supports

RANGE*nnn

(like N3SCD but the range specifies years, not days).

LOPT=(RANGE*[

number

])

If the years are

[number]

years apart or less then score 100 – if they are less than twice

[number]

years apart then score 50 – otherwise score 0.

[number]

can be in the range 0 to 32767.

The following option controls other aspects of the year comparison:

OPTION SCORES

VALUE TRANSYY,[number]

Compares the date after transposing the dates in the YY part of a year in the CCYY format and returns the

TRANSYY

value based on the match. For example, the year 1936 is compared to the year 1963.

If the number is greater than 0, the

TRANSYY

option is enabled and returns the score.

The

TRANSYY

value is returned if the difference is less than or equal to the value specified for the range in local options. If the Extended Range value is specified in local options, the value is adjusted as the extended range.
