LASTPOS




 >>--LASTPOS(needle,haystack--+---------+-)-----><
                              +-,start--+

LASTPOS returns the position of the last occurrence of one string, needle, 
in another, haystack. If the string needle is not found, 0 is returned. By 
default the search starts at the last character of haystack (that is, 
start=LENGTH(string)) and scans backwards. You can override this by 
specifying start, as the point at which the backward scan starts. start 
must be a positive whole number, and defaults to LENGTH(string) if larger 
than that value. 
Here are some examples: 

LASTPOS(' ','abc def ghi')      ->    8
LASTPOS(' ','abcdefghi')        ->    0
LASTPOS(' ','abc def ghi',7)    ->    4
