Pass parameters to rev app?

[Sarah]

Hi Bob,

Keep your hair on :-)  I don't have a solution but I have a few ideas 
you could try.

1. Sprinkle your scripts with "answer" commands to show you where you 
get to before it crashes.
2. Are you compiling into a single file or separate stack files? If the 
files are separate, then each file is it's own "mainStack" which may be 
causing a few problems.
3. If you are using lots of graphics, does your app have enough memory 
allocated?

Cheers,
Sarah
