Cam,

Sorry for not speaking up sooner, but I was curious what you all could come
up with. If you know where to look, you can find many concepts within the
actual source code. In this case, the ListView sample contains what is
needed:

CLASS HOUSEINFO
  18 BUFFER: szAddress
   9 BUFFER: szCity
    VARIABLE iPrice
    VARIABLE iBeds
    VARIABLE iBaths
END-CLASS

0 HOUSEINFO BUILDS[] rgHouseInfo[]
   ,Z" 100 Berry Lane " ,Z" Redmond " 175000 , 3 , 2 ,
   ,Z" 523 Apple Road " ,Z" Redmond " 125000 , 4 , 2 ,
   ,Z" 1212 Peach Street" ,Z" Redmond " 200000 , 4 , 3 ,
   ,Z" 22 Daffodil Lane " ,Z" Bellevue" 2500000 , 4 , 4 ,
   ,Z" 33542 Orchid Road" ,Z" Bellevue" 180000 , 3 , 2 ,
   ,Z" 64134 Lily Street" ,Z" Bellevue" 250000 , 4 , 3 ,
   ,Z" 33 Nicholas Lane " ,Z" Seattle " 350000 , 3 , 2 ,
   ,Z" 555 Tracy Road " ,Z" Seattle " 140000 , 3 , 2 ,
   ,Z" 446 Jean Street " ,Z" Seattle " 225000 , 4 , 3 ,
   0 ,

Note that the class instance is built with no data, and the data is added
after the header. You may not know ,Z" either. It lays down a null
terminated string.

The, the usage is very simple:

        5 rgHouseInfo[] iPrice @

BTW, Rick and I had to puzzle this out for a bit too! ;)
