Hi Folks,

The env array holds your environment variables:

% array names env
INFOPATH MANPATH HOME LOGNAME PWD TERM_PROGRAM __CF_USER_TEXT_ENCODING TERM SHELL SECURITYSESSIONID SHLVL OLDPWD TERM_PROGRAM_VERSION PATH _ PERL5LIB USER
% puts $env(HOME)
/Users/grahamellis
% puts $env(PWD)
/Users/grahamellis/dec07
% puts $env(SHELL)
/bin/bash

and indeed they are accessible by the expect script - see above.  There is no need for you to specially import them, but they do need to be exported from the parent shell so that they are available to you ...
