MyPos = Instr(4, SearchString, SearchChar, 1) ' A binary comparison starting at position 1. Returns 9. MyPos = Instr(1, SearchString, SearchChar, 0) ' Comparison is binary by default (last argument is omitted). MyPos = Instr(SearchString, SearchChar) ' Returns 9. MyPos = Instr(1, SearchString, "W") ' Returns 0.
