Some simple questions:

1) I am using SysEnviron (ignore misspellings) to detect environmental info
   about the Mac being used. My current list of MachineTypes goes up to
   the MacIIci = 9. Could anyone update me as to the MachineType returned
   for newer Macs?

2) How do I detect how much RAM is present (not how much is available,
   but how much is installed) It's not part of the info in the SysEnv
   record, and I can't find any help in Inside Mac 1-5.

3) I keep hearing about 32bit clean. Would someone explain what it means?
   I have a horrible feeling that all my applications are time-bombs since
   I have never worried about being 32 bit clean. If I use a high level
   language (Think C or Think Pascal) am I guaranteed to be 32 bit clean?

Thanks,
