Does there exist any RTL Delphi function to determine the position of the last occurrence of a char in a string?

You can use any character you want. Just make sure it's unique and doesn't appear in the string already. FIND(“@”,SUBSTITUTE(A2,”/”,”@”,LEN(A2)-LEN(SUBSTITUTE(A2,”/”,””))),1) – This part of the formula would give you the position of the last forward slash.
The rfind() method finds the last occurrence of the specified value. The rfind() method returns -1 if the value is not found. The rfind() method is almost the same as the rindex() method.
The idea is to use charAt() method of String class to find the first and last character in a string. The charAt() method accepts a parameter as an index of the character to be returned. The first character in a string is present at index zero and the last character in a string is present at index length of string-1 .
You can use string. back() to get a reference to the last character in the string. The last character of the string is the first character in the reversed string, so string. rbegin() will give you an iterator to the last character.
try the LastDelimiter function which is part of the SysUtils unit.
