system folders, screen sizes and mactcp questions

[Curt Stevens <stevens@sigi.cs.colorado.edu>]

I was wondering if anyone out there can help me with the following
problems...

I have written a system that needs to know where the system folder is. I
have done this for system 7 machines (using gestalt) but I need to do it
on 6.0.X machines as well. Can someone show me how to do this? Also how
do I check for the current system version?

I need to find out the sizes of the screens attached to the Mac running
my application (all screens if more than one).

I am using MacTCP (version 1.1) and the fixed MacTCP.lisp interface. 
After I open and close about 10 tcp streams I get the following error:

> Error: Error #-23048
> While executing: CCL::TCP-HOST-ADDRESS
> Type Command-. to abort.
See the RestartsI menu item for further choices.

Thanks VERY much for any assistance offered.
