Re: How to determine if Windows or Mac OS

[Jean-Luc Arnaud <jean-luc@filmsons.com>]

Testing:

iferr(externstr("uname"),E,externstr("ver"))

on Windows, I always got an error message, expecting ["", "Microsoft 
Windows [version 6.3.9600]"].
Same on Mac after swapping Expr1 and Expr2.

What am I doing wrong?
