The following statements are available in the FREQ procedure:
                         PROC FREQ
                          <options>   ; 
                         BY
                          variables   ; 
                         EXACT
                          statistic-options </ computation-options>   ; 
                         OUTPUT
                          <OUT=SAS-data-set> output-options   ; 
                         TABLES
                          requests </ options>   ; 
                         TEST
                          options   ; 
                         WEIGHT
                          variable </ option>   ; 
            
The PROC FREQ statement is the only required statement for the FREQ procedure. If you specify the following statements, PROC FREQ produces a one-way frequency table for each variable in the most recently created data set.
proc freq; run;
The rest of this section gives detailed syntax information for the BY, EXACT, OUTPUT, TABLES, TEST, and WEIGHT statements in alphabetical order after the description of the PROC FREQ statement. Table 3.3 summarizes the basic function of each PROC FREQ statement.
