(Alpha and Integrity servers) DBGTK_SCRATCH specifies how many
    pages of memory are allocated for the remote debugger. This
    memory is allocated only if remote debugging is enabled with the
    8000 boot flag. Normally, the default value is adequate, but if
    the remote debugger issues an error message, you should increase
    this value. See Writing OpenVMS Alpha Device Drivers in C (Margie
    Sherlock and Lenny S. Szubowicz, Digital Press, 1996). for more
    information. (This manual has been archived.)
