Bill, once you have a variable diminsioned as a particular TYPE, that
variable's space is already removed from DGROUP prior to execution.
That is to say, the space is already allocated, therefore, you would not
be able to notice the difference during runtime.  Take this example:

  TYPE Garbage
      Junk AS STRING * 255
  END TYPE

  DIM Junk AS Garbage
  PRINT FRE("")

This produces: 60936

  TYPE Garbage
      Junk AS STRING * 255
  END TYPE
  PRINT FRE("")

This produces: 61192, exactly 256 bytes more during runtime.
