TRANSITIVE_CLOSURE Statement
The TRANSITIVE_CLOSURE statement invokes an algorithm that calculates the transitive closure of an input graph.
Transitive closure is described in the section Transitive Closure.
You can specify the following options in the TRANSITIVE_CLOSURE statement:
-
LOGLEVEL=number
-
controls the amount of information that is displayed in the SAS log. Table 1.43 describes the valid values for this option.
