LVREP  OldString  NewString  CI|CS

    Replace all occurances of "OldString" with "NewString" in all
    the records of the current listview.

    BECAREFULL if the listview is a DataBase listview, because it
    may trash your records if the string you are replacing is 
    longer or shorter than the new string.

    Again, CS means "Case-Sensitive" and CI, not.
