Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

Each process may (or may not) have 3 kinds of action : AtRest,AlongStep, PostStep (for the exact meaning of this, see UserGuide).
Therefore the processManager handles 3 independent ordered lists of processes. The numbers in AddProcess() refer to these lists.
-1 means no action, 0 is the first of the list. For instance eplusAnnihilation 0,-1,4 is the first AtRest action, has no AlongStep action and is the fifth PostStep action.
NB. the Transportation itself IS a process which is mandatory and implicit (ie. registered by default)and must be the first. It correspond to AddProcess(new Transportation, -1,0,0)
