LVPUT  string

    will change the text of the current record the LV is at, 
    to what ever you give in "String".

    ex:
    lvuse gui 1
    lvgo #5
    lvput "This line has new text"

    If the ListView is a  DataBase , the old line will not be deleted
    and replaced with the new (like normal listviews) but will be
    copied over with the string given. The rest of the buffer, will
    be filled with blanks. 

    It's better to use %Fields that LVPut when dealing with DataBases.
