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. Brian Hawley
