Hi...
I've been trying to cut parts of sentences using string-left-trim.
The problem is that the function only accepts char, string, or sequence.

I've got this following code :

(setf sentence "1234 is a number")
(setf part (read-from-string sentence))
(setf sentence (string-left-trim part sentence))

> Error: value 1234 is not of the expected type SEQUENCE.

Is there anyway to remove those numbers??

Thanks heaps!!

Of course there is.  Check out SUBSEQ, for example (the second return
value from READ-FROM-STRING might prove useful here).

But READ (from string or otherwise) is unlikely to be the right way to
deal with input such as your "sentence".
