Ok, now I try it a little bit different. I try to write this code in
Racket/scheme:
Set WSHShell = WScript.CreateObject("WScript.Shell")
WSHShell.Environment("SYSTEM").item("var") = "value"
(require ffi/com)
(define WSHShell (com-create-instance "WScript.Shell"))
(define ENV (com-get-property WSHShell "Environment" ))
and here begins the Problem: It seems that I dont know how to give "SYSTEM"
parameter to Environment method. Is there a ffi specific syntax that I dont
explore yet??
yours,
