You have to read file and write it to different file, When you found the string that you want to delete, don't write it. WHen you finished, delete the original file and rename the new one.

Do you know how to read text files?  Is it possible to have multiple dates the same.  You could read the entire contents of the file into a string, replace the string with nothing, and then write the string back to the file.

try this. This is the code to remove the third string - 2004-09-30


                                                 str1 as string
                  str2 as string

                  str1 = "1999-01-01     2004-10-01    2004-09-30  2004-10-21"

            
                  length as int
                  fourthString as int

                  length = str1.Length()
                  fourthString = str1.IndexOf("2004-10-21")

                  str2 = str1.Remove(fourthString , length-fourthString) // This gives the final output string
