Changing environments


Hi,

at the moment I am trying to implement the procedure (ge <environment>)
which should change the current REP loop to the given environment.

The problem is, that I don't know how this could be done.  At the moment
an environment is a pair and (<environment-smob> . SCM_EOL) is the
top level environment.  I think all I have to do is to create a 
new top level environment and restart the REPL, no?  Are there any documents
that describe the "dynamic root" concept?
