You can specify the following statements with the OPTEX procedure. Items within the brackets $< >$ are optional.

PROC OPTEX <options> ;
CLASS class-variables ;
MODEL effects </ options> ;
BLOCKS block-specification <options> ;
EXAMINE <options> ;
GENERATE <options> ;
ID variables ;
OUTPUT OUT= SAS-data-set <options> ;

To generate a design, you have to use the PROC OPTEX and MODEL statements. You can use the other statements as needed. As the OPTEX procedure is interactive, you can use all statements (except the PROC OPTEX statement) after the first RUN statement.
