POS




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

POS returns the position of one string, needle, in another, haystack. (See 
also the LASTPOS function.) If the string needle is not found, 0 is 
returned. By default, the search starts at the first character of haystack 
(that is, the value of start is 1). You can override this by specifying 
start (which must be a positive whole number) as the point at which the 
search starts. 
Here are some examples: 

POS('day','Saturday')       ->    6
POS('x','abc def ghi')      ->    0
POS(' ','abc def ghi')      ->    4
POS(' ','abc def ghi',5)    ->    8
