Move Lines command

    Purpose:  Moves the range of lines specified by the first two line
              parameters ahead of the line specified in the third line
              parameter. The third parameter is not optional.

    Format:   [line],[line],lineM

    Remarks:  Use this command to move a block of data from one location to
              another. If the first or second line parameter is omitted, it
              will default to the current line. The lines are renumbered
              according to the direction of the move. For example:

              ,+25,100M

              moves the data from the current line plus 25 lines to line
              100. If the arguments overlap, an entry error is reported.
