Ok, I just had to go look.  You are right, you can't do that...  Ok, if
you can be POSTIVE that there will only be ONE instance of the threaded
code at any ONE time, (can you even run a thread more than once at any
one time?) then you can simply use global variables (a structure would
probably be better to keep it all tied up).

If you want to run multiple instances, try the following: (Note, this is
off the top of my head, and may contain bugs.) MAX_INSTANCES is the
number of times the thread can be running at any one time.

STRUCTURES:
struct threadInfo
{
        SHORT threadInUse
        SHORT myShort1, myShort2
        STRING myString
}

GLOBAL VARIABLES:
threadInfo myThreadInfo[MAX_INSTANCES]
SHORT startingThread       ;0=no >0 gives index into myThreadInfo

FUNCTION TO CALL THREAD:

VOID callThread1(SHORT myShort1, SHORT myShort2, STRING myString)
  SHORT loop
;If a thread is currently starting, enter a loop until thread
;completely starts
  while startingThread0
  endwhile

; hault any other attempts to start this thread
  startingThread=1

;Find an index in myThreadInfo that is not in use
  for loop=0 to MAX_INSTANCES-1
        if myThreadInfo[loop].threadInUse=0
                break
        endif
  endfor
;Check for maximum instances
  if loop=MAX_INSTANCES
        ERROR- MAXIMUM INSTANCES ALREADY RUNNING (Do whatever)
  endif
;Set data you want passed
  myThreadInfo[loop].myShort1=myShort1
  myThreadInfo[loop].myShort2=myShort2
  myThreadInfo[loop].myString1=myString1
  myThreadInfo[loop].threadInUse=1
;set startingThread to loop+1 so the thread knows where to find
;the data it needs in myThreadInfo.  (The +1 is to distinguish 0
;from meaning that a new thread is not being started)
  startingThread=loop+1

;START THE THREAD HERE WITH THE THREAD CALLS
end


THREAD CODE:
VOID thread1 ()

  SHORT useIndex
; Get the index from startingThread (-1 to counteract the +1 above)
  useIndex=startingThread-1
; Allow other instances to start
  startingThread=0

; data can now be referenced by myThreadInfo[useIndex].myShort1, or
; .myShort2, or .myString

;
;  YOUR THREAD CODE HERE
;

; release data from myThreadInfo for future use
  myThreadInfo[useIndex].threadInUse=0

; KILL YOUR THREAD HERE.
end

No idea.

I hope the code above helps...  It took me a while to enter it all.
