How to extract the levels of a categorical variable ?

[KarimaTouati]

Hello,

I am trying to read the names of a categorical variable in SAS and change it.

Is there any predefined function to extract variable levels in SAS ? 

[PaigeMiller]

proc sql;
     select distinct variablename from have;
quit;

Thank you PaigeMiller, I am looking for each level of my categorical variable and not an extraction of specific variables in my dataset.

The solution I gave does what you ask for.

PROC FREQ.

PROC FREQ DATA=sashelp.class;
TABLE age / OUT= want;
RUN;

The output is displayed and in the WANT data set. Change the variables in lower case to match your requirements.
