Ok, i want to separate the filename fromt he file path which is entered by the user. How would i do this? like...
i want to find the last / or \ in the path and then save all letters after that as the filename. Im not very good with the index function. could someone help? Smile

Index is good for the first occurence. if you want the last, I'd use a decreasing for loop.
code:

for decreasing i : length (path) .. 1
    if path (i) = "/" then
        filename := path (i + 1 .. *)
    end if
end for

You could also check for "\\" in the path if that's what you chose to use, but come on, just stick with the single slash in your pathnames.
