MEMORY information

  These variables show you the current memory information.

  $$MEM.CHIP   - the remaining chip memory
  $$MEM.FAST   - the remaining fast memory
  $$MEM.ALL    - all the remaining memory
  $$MEM.CLARGE - largest chip memory block
  $$MEM.FLARGE - largest fast mem block

  The last 2 are a little slow to get the info.
