The macro is dynamic to generate multiple Excel files containing the frequency results for each unique BY-group. (e.g., Type).
PROC SQL SELECT code is embedded inside a macro in this SAS example.
The SELECT query processes the column (passed in the macro parameter) and then create a macro variable with the number of unique (distinct) value in the column, and a macro variable with the list of unique values separated with “-“
The macro uses the <a href="https://www.9to5sas.com/proc-freq-in-sas/">PROC FREQ</a> procedure, an iterative macro %DO statement, a %SCAN function, and WHERE= data set option to dynamically send the results to an Excel spreadsheet for each BY-group.
