Example 9.1 Line-Printer Network Diagram
This example uses the data set WIDGET that was used in Example 4.2 in Chapter 4: The CPM Procedure, to illustrate the Activity-on-Node representation of the project. The following program invokes PROC NETDRAW twice. First,
the activity data set WIDGET is used as input to the procedure. The activity and successor information is identified using the ACTIVITY= and SUCCESSOR=
options in the ACTNET statement. The LINEPRINTER option is specified, producing the line-printer network diagram shown in
Output 9.1.1.

Next, PROC CPM is invoked to schedule the project, and the resulting Schedule data set is used as input to the NETDRAW procedure.
In addition to the ACTIVITY= and SUCCESSOR= options, the DURATION= option is used in the ACTNET statement. The DURATION= option
adds the values of the DURATION variable within each node of the network. The procedure also displays the values of the E_START, E_FINISH, L_START, L_FINISH, T_FLOAT, and F_FLOAT variables within each node. The network is displayed in Output 9.1.2.
