RE: Subfile question.

["hendry tionardi" <ahen75@xxxxxxxxxxx>]

I would asked another quiestion about subfile again.

If i had to read 2000 record of file and using subfile, an once time display 
only can be 20 record.(my dds file only can fit 20 record)

Did i make the subfile size as big as that record number size(2000),
Or i just make the subfile size as big as subfile page size (20)?

If and the subfilesize 2000, i think it won't be a problem for page up and 
page down, because of subfile can handle it.

But let's say if the size of record, we don't had know how big is this file, 
like we created a program for banking application that searching for bank 
account using name, how subfile handle it?
Because we don't know how many record of the file, and how subfile handle 
the roll up , roll down ??
