As an absolute beginner I'm not able to calculate the number of days
  between today and a given date in a database (dBase III+ table).
  After weeks of experimenting I'm able to calculate the number of
  days between two dates with TRUNC ( date1 - date2 ), but when I
  replace one of those variables with the datefield from the table,
  things go wrong.
  I've tried:
  TRUNC( table1.FieldByName( 'geb' ) - date2 );
  TRUNC( date1 - date2 );
  I've declare date2 as...
  date2 := table1.FieldByName( 'geb' ).AsString;
  date2 := table1.FieldByName( 'geb' ).AsDate;
  date2 := table1.FieldByName( 'geb' ).AsReal;
  In my former language I just simply used the very simple frase:
  Days := date1 - date2
  And that's all... For a language that's supposed to be RAD, there
  must be an equivalent....
  Delphi is supposed to be RAD. But for me with al my
  cursing ans swearing that abbreviation now means 'Raising All
  Demons' to my poor family....
  Plesase save their poor souls and help me to overcome this problem.
  Please give me a working example, cause I've seen every corner of
  the helpfiles by now...
  I'm using Delphi 1.0
  Thanx by Tom (son), Anita (wife) and Kikomas (dog)...
