I would like to be able to get at all of the environment variables (whether it is the shell environment variables or the CGI environment variables or something else). What object/class would I use for that ?

o wait, i think i know this:

Smalltalk getenv: 'foo'
Smalltalk getenv: 'bar'

Is there something that will get all the environment variables and store it in an Array or something like that ? Using the approach above, say in a CGI environment when I'm trying to debug, I just want it to print every environment variable as I probably do not know what I would be looking for but am hoping
that something in the environment will give me some guidance.

Did that make sense ?

Perl, Tcl, and PHP store the environment variables in an associative array which can then be poked and peeked at (yes the usage of the two words was intentional use of BASIC). Scheme also supports this with a recent enhancement to the language, SRFI-98.

Is there some way to do something similar ? Maybe there is a message "getenvAll" ? I couldn't find it and there doesn't seem to be much documentation for getenv on site.
