I may have messed up the "path" variable in Environment Variables

[idiom]

I may have messed up the "path" variable in "Environment Variables" under system properties in Windows.
Right now this is all there is in the path:
c:\Borland\Bcc55
I deleted the other stuff when I put the borland path, if that other stuff needs to be there how do I restore it?

This is the error I get when I try to edit my bcc32.cfg file from the "command" screen(dos shell).

C:\>cd borland

C:\BORLAND>cd bcc55

C:\BORLAND\BCC55>cd bin

C:\BORLAND\BCC55\BIN>edit bcc32.cfg
