Once you get the basic algorithm, MERGE is a "piece of cake". ... A BY statement can name one or more variables, and the SAS system expects the data sets to be ordered by the values of the variables named in this statement. When combining data sets, each data set must include the BY variable or variables. ... you can either rename the variables ...

A macro variable is a variable whose value is stored within the macro symbol table. When the macro variable is used in SAS code, SAS substitutes the value of the macro variable into the SAS code. SAS macro variables are distinguished by the "&" sign before the variable name. Note that all SAS macro variables are stored as text strings.

SAS-DQ does not provide functions or procedures to automatically combine the two sets of dupe groups (those based on each “index”). We formulated an algorithm to perform this task using Base SAS. In creating index variables for the algorithm, the index (1 or 2) having the greater number of dupe groups should be index1.

When you use a BY statement in your data step, SAS creates variables called ‘FIRST.’ and ‘LAST.’. These variables identify the first and last observation with each value of the variables on the BY statement. This is also great to use if you have multiple observations for people and you only want the first one or you only want the last one.
