HEADNODE Statement
-
HEADNODE variable;
-
HEAD variable;
-
TONODE variable;
-
TO variable;
The HEADNODE statement specifies the SAS variable that must be present in the ARCDATA=
data set that contains the names of nodes toward which arcs are directed. It is not necessary to have a HEADNODE statement
if the name of the SAS variable is _HEAD_ or _TO_. The HEADNODE variable must have character values.
There should be no HEAD statement if you are solving an LP.
