1)  Termcap entry for 520ST emulating a vt52:
    The following termcap entry works fine with our 4.2bsd system on
    a VAX 11/780. (I have a B&W high res monitor and this termcap
    has been used at 1200 baud only.)

    it solves many of the mysterious problems experienced while
    using the "standard" vt52 termcap (incorrectly positioned cursor etc.)
2)  ST BASIC: READING MOUSE POSITION
    The example given for the command GEMSYS (on page C-57) in the
    BASIC manual does just this.
3)  ST BASIC: WAVE COMMAND
    The ENABLE parameter has its bits turned ON by 1's and OFF by 0's.
    The manual says exactly the opposite.
