ri is your friend. We'd rather choose separated document command
rather than consuming interpreter memory. Integrating ri into irb
might be a good idea though.

Actually this seems to be what the "help" method does that Michael
mentioned. When I type "help String" in IRB I get the same result as
from "ri String" on command line, i.e. the doc in a pager. For methods
you have to do "help 'String#length'".

Thanks, Michael!

Kind regards

robert
