ID Statement
- ID variables;
The ID statement specifies variables to identify observations in
error messages or other listings and in the OUT= data set.
The ID variables are normally SAS date or datetime variables.
If more than one ID variable is used, the first variable is
used to identify the observations; the remaining variables
are added to the OUT= data set.
