REREPLACE |
Description Uses a regular expression (RE) to search a string for a string pattern and replace it with another. The search is case-sensitive.
Returns If the scope parameter is set to one, returns a string with the first occurrence of the regular expression replaced by the value of substring. If the scope parameter is set to all, returns a string with all occurrences of the regular expression replaced by the value of substring. If the function finds no matches, it returns a copy of the string unchanged.
