Expanding on Nillen's reply: in the scripting language, you can also use partial paths in commands and identifiers and these will be relative to $mircdir. This means that if you place the file cow.txt in $mircdir, you can access it using just $read(cow.txt). If you place cow.txt in folder "moo" in $mircdir, you can access it using $read(moo\cow.txt). In other words, you do not need to specify the full path, which makes the script more portable.
