Re: Screen Scraping and hoging system resources

["David Bulog" <d2ba@xxxxxxxxxx>]

Thanks JT,
It is no longer economical to redesign the screen scraper's as there
is aboubt 30 differient applications--a least two years work in that
lot so tuning at the AS/400 end is our only option.

Basicly a screen scraper is a good way to go for a non technical person.
like myself as a first step.
HLLAPI or Object X is so easy to use that you dont even need to be
a programmer.In my case I wrote these legacy applications back in 1999 as my
first programs. They all typically follow a theme--customer
phones front office rep-rep inputs instructions into green screen form-
Screen scraper process's the job's often between AS/400, Mainframe's
Unix box's---Rumba makes it so easy there terminal emulaters are all
designed to talk to each other via HLLAPI or Object X

Of course there is always a better way to do then using a screen scraper
but in our case they do what they are supposed to do ie emulate 100's
of real data entry people.The budget is no longer there for a re-write


cheers Dave
