DBAMNU Parameters EXP_FCT

  You may change the size of the database by a percentage fac-
  tor. Values must be between -99% and +1000%. A factor of 0
  should leave the database at its current size, although snap-
  shot files may be reduced in size. A factor of -99% should
  result is a database with area files only 1% of the previous
  size. A value of +1000% should result in a database with area
  files 10 times their previous size.
