In Perl, backslashes escape the character that follows them, just like in C. If
you want a literal backslash, you need either "\\" or '\':
system("command.com copy /C d:\\test\\input.ps e:\\test\\output.ps");
or
system('command.com copy /C d:\test\input.ps e:\test\output.ps');
The latter example is probably perferable.
But that still doesn't explain why it lists the file as "D:\TEST\INPUT.PS",
which seems correct (I would expect it to say something like "D: EST NPUT.PS".)
But I've never messed with DOS, so I can't be sure.
