this will work on the Windows installation. There the documentation is 
installed in the "doc"
subdirectory of the Rexx installation directory (which the Windows environment 
variable named
"REXX_HOME" points to).

So on Windows, if you enter '?' in rexxtry.rex, you get the rexxref.pdf window. 
(This part of
rexxtry.rex will not be executed on non-Windows installations.)
