NEW DOS EXTENDER FOR CA-CLIPPER ANNOUNCED

  DALLAS, TEXAS - An unprecedented collaboration between third party
  developers SofDesign International, Inc., Dallas, TX and ObjecTech, Inc.,
  Glen Rock, NJ has resulted in ExoSpace(tm), the first DOS extender for
  CA-Clipper applications.  The powerful new product frees CA-Clipper
  applications from the DOS 640K limitation.

  According to ExoSpace representative Jon Cole, the new product is
  designed to enhance the performance and viability of CA-Clipper by
  increasing addressable memory from 640K to 16 megabytes.  It accomplishes
  this by running the application in protected mode, giving CA-Clipper
  direct access to extended memory.  This reduces or eliminates the need for
  virtual memory swapping.  In addition, applications run with less than
  256K of free DOS memory, solving low memory problems caused by network
  shells, terminal emulators, or other resident programs.

  Users of large applications, networks, or third party products
  realize the greatest benefits, noted Cole.  ExoSpace increases overall
  performance while eliminating nearly all memory problems.  Users are able
  to create significantly larger applications than previously possible with
  CA-Clipper.  Most existing applications require no coding changes.

  ExoSpace includes a protected mode linker which allows all code and
  data to be overlaid, but only if necessary.  When enough memory is
  available, the entire application and all program data can reside in
  memory.  ExoSpace can be used on computers with an 80286 or higher
  microprocessor and a minimum of 2 megabytes of RAM.  Because applications
  run in protected mode, obscure bugs in C and Assembler code are easier for
  third party developers to find and eliminate.

  Both SofDesign International and ObjecTech have extensive experience
  with developing successful CA-Clipper add-on products.  Other SofDesign
  products include ProVision:Windows, ProVision:Backup, OverLay(), and
  ProClip.  ObjecTech's award- winning product, Class(y), is an
  object-oriented extension for CA-Clipper.
