PROC FACTEX Statement

Details of the FACTEX Procedure

PROC FACTEX <options> ;: You use the PROC FACTEX statement to invoke the FACTEX procedure. The following options are available:
NAMELEN: specifies the length of effect names in tables and output data sets to be n characters long, where n is a value between 20 and 200 characters. The default length is 20 characters.
NOCHECK: suppresses a technique for limiting the amount of search required to find a design. The technique dramatically reduces the search time by pruning branches of the search tree that are unlikely to contain the specified design, but in rare cases it can keep the FACTEX procedure from finding a design that does, in fact, exist. The NOCHECK option turns off this technique at the potential cost of an increase in run time. Note, however, that the run time is always bounded by the TIME= option or its default value. For more on the NOCHECK option, see "Speeding up the Search" .
TIME=t
SECONDS=t: specifies the maximum number of seconds to spend on the search. The default is 60 seconds.
