Attrib does not work in Windows NT NTFS and stuff, y'know.

[Jonathan Simpson]

Attrib works fine in NT... from the command line anyway. Make sure you load CMD.EXE under NT to use attrib, instead of command....
SHELL "cmd.exe /c attrib * -r"
for example.
You can use
ENVIRON("COMSPEC") to get the full path to CMD.EXE under NT (also a decent way to detect an NT based OS.
