This isn't the case. The message re actions executing more than 200000 times

came up from the conditional test.

if <condition>

  goto next frame

else 

  load move stuff

end if


next frame:

goto previous frame


I found that after interval was greater than ~7000, I'd fail for this

reason. Note that we've broken out of the code block when we go to next

frame and then enter it again.


Another thing I noticed was that my buttons weren't working while bouncing

between frames. So what I finally did was pad in about 10 frames with a goto

label: "code block" at the tenth. This ensured I was spending 90% of my time

outside the code and I can now go beyond 20 seconds, have buttons that work,

and all is well. 


EXCEPT -- I'm still bothered by that 200,000 actions limit. From this

behavior it looks like the action list refers to all actions in the movie.

It certainly doesn't refer to iterations within a single code block. I

wonder if it could kick in under other circumstances such as a game which

was very processor intensive (multiple timing loops, some kind of

heuristics, other iterative evaluation processes). I'd still like it removed

regardless. If I want to write an infinite loop I should be able to. Heck,

half the programs I've written have been infinite loops with some hack to

escape them. Used to write dbase with Do While(.true.) wrapping the whole

thing. Exit button would set .true.=.false.


Another potential issue (dare I say bug?) seems to be in the comparison

operators. I'll have to go back and check this again, but it looks like the

construct ((a+b)<=c) is broken. You have to do d=a+b then (d<=c). 


Anyone else seeing any of this?
