Function right() returns the string from the end position, not the start.

Example...
msg = "This is a test"
print right(msg,6)

returns "a test"

Try this test:


left(msg,x) gives you the leftmost x characters
right(msg,x) gives you the righmost x characters
mid(msg,x,y) gives you the y most characters starting at position x.
mid(msg, x) gives you zero characters because y is zero. Other basics would give you the remainder of the string if y is omitted.



All lines are printed to the console but only the first two lines appear in the web interface!

If that is the way it should work then the documentation is wrong.

I agree that the documentation needs improving.

If you want the right part of a string starting at position x and returning the remainder of the string, you can use

where 99 is any number that is longer than the longest string.
