   SNAP is  based on  Bob Andersson's LAP.COM.   It saves an image of the ENV,
RCP,  FCP,  IOP,  NDR,  path,  and quiet flag, plus a small loader to the file
named on the command line.  That is,  rather than installing itself, it writes
another program  to reload the packages.   The output file is about 2k smaller
than LAP.  Error checking is minimal.

   Usage:  SNAP SYS       <-- save current packages to file SYS.COM
           LDR OTHER.ENV, OTHER.RCP, OTHER.FCP, OTHER.NDR
           SNAP OTHER     <-- save this version to OTHER.COM
           SYS            <-- reload all original packages at once
           OTHER          <-- run the other configuration

SNAP Notes:

   a. Note that,  although the space allocated  to each package may vary,  you
      cannot load one size system over another with SNAP.

   b. The  same  scheme  is  followed  as  that  in  LAP.COM  -  disabling  of 
      interrupts, loading the image, calling the IOP initialization routine at
      IOPBASE+9, and enabling interrupts.
