PROC PLAN Statement
PROC PLAN <options> ;

The PROC PLAN statement starts the PLAN procedure and, optionally, specifies a random number seed or a default method for selecting levels of factors. By default, the procedure uses a random number seed generated from reading the time of day from the computer’s clock and randomly selects levels of factors. These defaults can be modified with the SEED= and ORDERED options, respectively. Unlike many SAS/STAT procedures, the PLAN procedure does not have a DATA= option in the PROC statement; in this procedure, both the input and output data sets are specified in the OUTPUT statement.

You can specify the following options in the PROC PLAN statement:

SEED=number

specifies an integer used to start the pseudo-random number generator for selecting factor levels randomly. If you do not specify a seed, or if you specify a value less than or equal to zero, the seed is by default generated from reading the time of day from the computer’s clock.

ORDERED

selects the levels of the factor as the integers in order. For more detail, see Selection-Types and Specifying Factor Structures.
