The OPTNET Procedure

TRANSITIVE_CLOSURE < options > ;

TRANSCL < options > ;

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 2.22 describes the valid values for this option.

Table 2.22: Values for LOGLEVEL= Option

number	string	Description
0	NONE	Turns off all algorithm-related messages in the SAS log
1	BASIC	Displays a basic summary of the algorithmic processing
2	MODERATE	Displays a summary of the algorithmic processing
3	AGGRESSIVE	Displays a detailed summary of the algorithmic processing

The default is the value that is specified in the LOGLEVEL= option in the PROC OPTNET statement (or BASIC if that option is not specified).

OUT=SAS-data-set

specifies the output data set to contain the transitive closure results.
