LotusScript finds the first occurrence of a string from the right

Using the Instr function can help to find the first occurrence of a string from the left. However, if you want to find the first occurrence from the right, you can use this LotusScript code.

Let's suppose that you need to find the position of a particular string from the right (like I did). I found that I could not use the Instr function for this because it only searches for a string from the left. For example, in the string "aasha," the Instr function returns a "1" when given the letter "a." However, if you need to find the last occurrence of "a," it should return a "5."

The following steps and LotusScript code can allow you to search a string from the right.

  1. Create a field and name it "stringlist."
  2. Give it a default value that contains the character "a." This can be changed according to requirements, but corresponding changes must be also made in the code.
  3. Create a button and write the code in the click event of the button.

After clicking the button, a message box with the position of the string will appear.
