+======Synopsis:======
+$[[ftell]](//file descriptor//)
+======Technical:======
+This function returns the current position of the file pointer, measured
+in bytes from the beginning of the file.  This value can be used to save
+your position in the file, and you can later use
+    $fseek(//file descriptor// SET //ftell-value//)
+to resume your place.
+The //file descriptor// must have been a value previously returned by
+the [[open]] function.
+======Returns:======
+<file>
+-1   Error: //file descriptor// was not previously returned by [[open]], or //anchor// is not supported.
+</file>
