Examples

1.     Print (A) :: IT := 365; Annual;

   Each 365 unit times the procedure Annual is called (for instance to print a report of the state of the model). The node must be activated for the first time from other node or from the INIT section.

2.     GraphProPri (A) ::   IT := 0.125;
                            GRAPH(0, 50, BLACK, TIME: 6: 1, WHITE;
                                  Prod: 7: 1, Production, 0, 1000, RED;
                                  Price: 7: 1, PriceInd, 0, 2, Yellow);

   Each interval time of 0.125 units (8 times per year) points with the new values of Prod and Price are added to the time graphic and united by a line to the previous point. The node must be activated for the first time from other nodes or from the INIT section.

3.     NewStr (A) NewSource ::  IT := 0.5;
                                If CondStCh THEN
                                            BEGIN
                                              ACT(NewSource, 0);
                                              CREATE(MessSource)
                                              SENDTO(NewSource);
                                              DEACT(Inst3);
                                              ACT(Proc4, 12);
                                              STAT;
                                              CLRSTAT;
                                            END;

   Each 0.5 units of time the boolean function CondStCh (that may compute conditions for a structural change) is evaluated. If it is TRUE, the nodes NewSource and, with a delay, Proc4 are activated. The Inst3 is deactivated. A message is sent to the newly activated node. The statistics are displayed and then initialized for a new statistical gathering.
