Swapping to EMS/Disk

        Using each of the following features involves running a
program that is external to Family Scrapbook:

        Reindex
        DOS Shell
        Notes Editor
        Gedcom I/O

        When one of these is run, Family Scrapbook stays in memory
and temporarily drops to DOS to invoke it.  Family Scrapbook will 
use about 250K of memory.  If the swap function is enabled, it will 
only use about 4K of memory.  If the swap function is enabled, it will 
first try to swap Family Scrapbook to EMS.  If it is unsuccessful, it 
will swap to disk.

        EMS stands for Expanded Memory Specification or LIM
memory (Lotus/Intel/Microsoft).  EMS (or LIM) exists in different 
versions.  Family Scrapbook has been tested with version 4.0 of EMS 
and was successful.  It might work with older versions, but it hasn't 
been tested on it.  Note: EMS is not the Extended memory that is 
found on most 80286 (and some higher) microprocessor based 
computers.  Family Scrapbook does not use Extended memory.

Pros of turning on the swap function:

        1. Program gets more memory to operate in.
        2. Increased memory might mean increased speed.

Cons of turning on the swap function:

        1. Program loads and returns slower.
        2. If you don't have EMS, it requires about 250K of disk space
        for use by a temporary file.

Useful tips:

        1. Don't use swap unless you really need it.
        2. If you are swapping to disk, try using a ramdisk to speed
        up swapping.  You can specify what drive to use in the Program
        Setup screen.
