Table 7 nI Comparison Function Parameters

Parameter 

Description 

switch

Specifies whether a relative distance calculation or a direct string comparison is used. Specify “y” to use a relative distance calculation; specify “n” to use a string comparison. 

range 

The greatest difference between two integers at which the values could still be considered a possible match. When the difference between two numbers is greater than the relative distance, the numbers are considered a non-match (the weight becomes zero when the actual difference is the relative distance plus one).
