strrindex — Return the position of the last occurence of a string in another string
Return the position of the last occurence of S2 in S1, or -1 if not found. If S2 is empty, the length of S1 is returned. strrindex runs at init time only.
Here is an example of the strrindex opcode. It uses the file strrindex.csd.
