BtrvStepFirst (DataVar,Handle)

BtrvStepFirst goes to the first physical record of the file and reads the record into DataVar. DataVar is a MarxMenu variable and the data read creates an array of the fields stored on disk.


Example:

   Var Fields, Handle, DataVar
   ReadAscTextFile('FIELDS.TXT',Fields)
   Handle = BtrvOpen('BBSUSER.BTD',Fields)

   BtrvStepFirst(DataVar,Handle)
   while BrtvResult = 0
      loop DataVar
         Write LoopVal ' '
      endloop
      Writeln
      BtrvStepNext(DataVar,Handle)
   EndWhile

This example dumps the contents of a file to the screen.
