Re: Hypothetical Question

[Doug Donalson]

You're using the latest swarm.dll, yes?

I don't really know, I'm using the 2.1.1 install.  Are there any Objc
updates to that?

I realized that I had a tool that you showed me that I wasn't using when I
printed the schedule, xprint.  I added that to my "schedule printer" and got
an interesting result.  First the basic code of printSchedule (note that it
is just a version of the asynchronous schedule code Roger wrote for me) and
then the results of a schedule print.

The Code:

- printSchedule
{

timeval_t timeOfAction,actionAtTime;
double presentTime;
id index,groupIndex;
timeval_t nextSuperEvent,nextSubEvent;
int eventCount=0;


// return NULL;
  index = [eventSchedule begin: [self getZone] ];
  while ( (actionAtTime = [index next]) )
  {

         puts("Group break");
         timeOfAction = (timeval_t) [index getKey];  // key of member is
time value
         if ( [actionAtTime getClass] == id_ActionConcurrent_c )
         {
            groupIndex = [((ActionConcurrent_c
*)actionAtTime)->concurrentGroup
                   begin: [self getZone]];
           while ( (actionAtTime = [groupIndex next]) )
           {
                printf("at time: %u.%u action is: %0#8x   \n"
                     ,timeOfAction,[groupIndex getKey],actionAtTime);
                fflush(stdout);
                 xprint(actionAtTime);
                 fflush(stdout);
                 eventCount++;
                 if( eventCount > 20 )
                return NULL;
           }
            [groupIndex drop];
     }
     else
     {
         printf( "at time: %u  action is:
%0#8x\n",timeOfAction,actionAtTime );
     }
  }
   [index drop];
   return NULL;
}

Here is a snipit of the schedule print containing the errent action:

Group break

[ActionConcurrent_c 0x4bc7f28: ActionConcurrent_c concurrentGroup:0x518f718:
ConcurrentGroup_c]

Are the xprints that have the form [ActionConcurrent...] concurrent groups
in the subschedule?  If so is there a way to modify my printSchedule code to
print out actions contained in a concurrent group in a subschedule?
Otherwise, what is xprint telling me?

I have just made a text document of the execution of events leading up to
the error
and am attaching it.  It shows where the error is occuring and I annotated
it as best I
could.  It was cut and pasted from the schedule print format from above.  I
f I can
get into what I am assuming is the concurrent group in the subschedule then
I can probably figure out what is going on.  (This email has been in work
for
about 3 hours. [grin])
