With /Command or /Pro you can access the C getenv function
from the C library, or you can use the call function like
a: "" call/output "echo %PATH%" a
or for all variables
a: "" call/output "set" a
With all REBOLs you can pass them on the command line like
rebol.exe --do "app-paths: {%PATH%}" blah.r
and even preprocess them like this
rebol.exe --do "app-paths: parse {%PATH%} {;}" blah.r
which returns the PATH variable broken into its components.
I used a trick like the latter one to implement REBOL batch
files that could be anywhere in the PATH directories.
A little late, but it might help.
