Par2: How to start threads automatically at startup?

I would suggest using Notify() & Notification() to work through your
stack of procedures. This is the method I've use in AFE since the
introduction of real threads and running into the same problem you
did. AFE starts 12 threads when it first loads!
MainThread LONG
NotifyCode UNSIGNED
NotifyThread SIGNED
NotifyParam LONG
OPEN(AppFrame)
ACCEPT
CASE EVENT()
OF EVENT:OpenWindow
MainThread = THREAD()
NOTIFY( 1, MainThread, 1 )
OF EVENT:Notify
IF NOTIFICATION(NotifyCode,NotifyThread,NotifyParam)
IF NotifyCode = 1
EXECUTE NotifyParam
tDrawCover = START(Draw_CoverSheet,50000)
tDrawPages = START(Draw_FaxPages,50000)
tAppendTIF = START(AppendTIF,50000)
tRefreshSystem = START(RefreshSystem,30000)
tBuildQueue = START(BuildQueue,20000)
tScheduleFax = START(ScheduleFax,20000)
tCompletedFax = START(CompletedFax,20000)
tFailedFax = START(FailedFax,20000)
tFailedSchedule = START(FailedSchedule,20000)
tPrintReport = START(PrintReport,20000)
tHandleXref = START(HandleXref,20000)
tFaxCore = START(FaxCore,40000)
END
END
END
