NewString := DELSTR(String, Position[, Length])
Parameters
- String
Type: Text constant or code The input string.
- Position
Type: Integer The position of the first character that you want to delete. Position must be greater than zero (0). If Position exceeds the length of String, DELSTR returns the original string, unchanged.
- Length

Property Value/Return Value

If you omit Length and Position is greater than the length of String, then String is returned unchanged.
