## MakeCel out of memory

Q: I'm having trouble running the ``MakeCel utility from the MPW shell. It comes back with an error stating that it is out of memory and cannot swap to a shell (two errors in total).

A: Try increasing MPW's memory to something really big (30 MB). If MakeCel still doesn't work, it's probably not really a memory problem.

  - If the large amount of RAM works, start scaling it back until the problem reappears. Then bump it back up again.

  - If that doesn't work, there may be a bug in MakeCel. Try running it with a different image, something small and simple.

## Documentation for PPM tools

Q: Where can I find documentation for the PPM tools?

A: Documentation for the public domain PPM tools are provided on-line in the same folder as the tool itself. Documentation for the 3DO PPM tools is available on-line, in the release notes for Toolkit 1.5 and will be part of Getting Started With 3DO Portfolio.
