Nathan,

I think the problem with screen scraping is that the new end user
application is limited to the data provided by the host application that is
being scraped from.  The subfile record may only contain customer name and
not customer number.  Also, the subfile records may only contain a page of
the records that the user is interested in working with. ( how can the user
sort on order amount when the display buffer being scraped from only
contains 10 of the 100 orders of the customer? )  Whether the data is
scraped from a screen or from a pre dspf buffer, it still has the same
limitations.
