                   from the parameter table by I-DEAS Test.
 
          9        Any Record With All 0.0's Data Entries Need Not (But
                      May) Appear.
 
          10       A Direct Result Of 9 Is That If No Records 9 And 10
                      Appear, All Data For The Data Set Is 0.0.
 
          11       When New Analysis Types Are Added, Record 7 Fields 1
                      And 2 Are Always > Or = 1 With Dummy Integer And
                      Real Zero Data If Data Is Not Required. If Complex
                      Data Is Needed, It Is Treated As Two Real Numbers,
                      Real Part Followed By Imaginary Point.
