>>-POS--(--needle--,--haystack--+----------+--)----------------><
'-,--start-'
returns the position of one string,
needle, in
another,
haystack. (See also the INDEX and LASTPOS functions.)
Returns
0 if
needle is the null string or is not
found or if
start is greater than the length of
haystack.
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), the point at which the search starts.
