Altova MapForce 2021 Professional Edition

Returns the position of the last occurrence of substr within string. By default, the function starts the search from the first character, which has position (index) 1, and ends the search at the last character, but you can optionally specify an ending index. If substr cannot be found, then the function returns 0.
