Yes, I've done that in most cases, and tested $^O to know what to do. In the
case I noticed I was calling a Windows program by a Windows path and had no
reason to write it differently. So if I want to run that particular script
under Cygwin Perl I could branch to an sh-compatible call, or actually I
rather like the idea of "standardising" on system("cmd /c
...") even if it does waste a cmd.exe invocation :)

Actually I had no idea - and I must say that rather dissuades me from using
it. I have no other need for an X server, and I quite like the way AS
Perl/Tk gives me Windows controls on Windows and X widgets on X. (I have
installed AS Perl on Solaris and run some of my Perl/Tk scripts there
without problem. Thanks for pointing that out.
