The DQMATCH Procedure

The DQMATCH procedure creates match codes in an output data set for specified input character variables. The procedure can also generate cluster numbers for input values that generate identical match codes. Cluster numbers are not assigned to input values that generate unique match codes. Input values that generate a unique match code (no cluster number) can be excluded from the output data set. Blank values can be retained in the output data set. Blank values can receive a cluster number.

Match codes are created based on a specified match definition in a specified locale.

A specified sensitivity level determines the amount of information in the match codes. The amount of information in the match codes determines the number of clusters and the number of members in each cluster. Higher sensitivity levels produce fewer clusters, with fewer members per cluster. Use higher sensitivities when you need matches that are more exact. Use lower sensitivity levels to sort data into general categories or to capture all values that use different spellings to convey the same information.
