212224b4cf* Added the primitive (environ): returns an alist of (string x string) as obtained from the system environ. * Added the primitive env: (env "key") retrieves the env value associated with key (env "key" "val") sets the env value assocuated with key to val (env "key" "val" overwrite?) same as above but it does not overwrite an existing value of overwrite? is #f.
