---------------------------------------------------------- At the end of the input file, a START card is mandatory in order to actually start the calculation. That card must indicate also the number of particle histories requested. The run, however, may be completed before all the histories have been handled in two cases: if a time limit has been met (on some systems) or if a "stop file" is created by the user (see instructions in Note 2 to option START). The START card is optionally followed by a STOP card. For example, if the user wants to generate 100000 histories, the input file can be closed with the following two cards:*...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8START 100000.0 STOP
