  //      space which has been reallocated as conventional memory).
  //      Increase the number of variables to be allocated.
  //
  // If you still cannot solve your problem, keep yelling at CA .
  //
  // Note that this is not a catch all solution.  There are many things
  // which eat up DGROUP, and many combinations which lead to peril:
  //   a. C and ASM static data.
  //   b. CPU stack.
  //   c. Eval Stack.
  //   d. Memvar Table.
  //   e. "last resort" conventional memory.
  // The total size of DGROUP is 64K.  It is configured so that the
  // Eval Stack grows toward the Memvar Table.  If it overruns it, you get
  // UE 667.  If there is a large piece of memory in between the Eval Stack
  // and the Memvar Table, and the VMM sees that after some time of program
  // execution that your program has not accessed this area, it will
  // allocate it as conventional memory as a last resort. After that point,
  // if more local variables are instantiated, and the Eval Stack overruns
  // the VMM conventional memory, you get UE 668.
  //
  // If, at some point, the VMM attempts to allocate conventional memory,
  // and there is none left, you get "Conventional Memory Exhausted".
  //
  // Incidentially, UE 669 is what you get when the Memvar Tablecannot be
  // expanded for the same reason.  UE 650 processor stack fault, is caused
  // by the cpu call stack growing too large, its size can be controlled with
  // the linker /STACK command, or equivelent (SET PROCEDURE DEPTH, Etc.).
