lastPos

>>-lastPos(needle-+--------+-)---------------------------------><
                  +-,start-+

Returns the position of the last occurrence of a string, [needle] , in the receiving buffer. (See also .) It returns 0 if [needle] is the null string or not found. By default, the search starts at the last character of the receiving buffer and scans backward. You can override this by specifying [start] , the point at which the backward scan starts. The [start] must be a positive whole number and defaults to receiving_buffer~length if larger than that value or omitted.
