instr function in reverse ??? - doppler - 02-10-2023

Here is a bit to knock around.

I have a standard routine I use to find the last occurrence of a character in a string. Happens to be "\".  Using a do loop to search out a string is easy.  Looking to make it faster.  Would it be beneficial, to specify the direction of search in instr function?  Forward or reverse order.

I am think more of an enhancement to instr function.  if it's more trouble than it's worth, I will just continue with what I got.
