Use smart insert and delete (providing terminal has those features). This option should be selected whenever the comment area is more than about 5 lines high and there will be no text on the screen to either the left or right of the memo pad area. It is important that no screen display exists to either side of the memo because INMEMO will use the terminal's insert and delete line operations to perform certain display operations, which will shift or delete information outside of the memo window. You can prevent this by simply not including MMO'LID in the opcode.
