Re: How can I STOP a cursed recursion?

Hi

Sorry, stuff got a bit garbled.

I tend to use functions, because its easier to break out of a function than 
a procedure.

This is the way I do it

Generally you need a global indicator variable. This tells the loop, and all
previous loop iterations to stop.

An infinite loop within the procedure

integer break_free --this is global to the program
break_free = 0

procedure foo()

while 1 do
   if break_free = 1 then
       exit
   end if

   --do stuff

   --are conditions met to exit loop
   if conditions met then
        break_free = 1
   end if

   foo()

end while


end procedure

Note the position of loop testing, and setting the global break free
variable - if you've recursed (?) 10 times, then you exit the loop 10 times

You must also reset break_free to 0 immediately after calling foo() for the
first time
