Screen scraping is a method that allows a (typically) thin client to process in the middle of a cics/3270 conversation. On the mainframe (CICS) side the conversation it appears that there is a 3270 terminal. On the client (windows pc), there is gui presentation rather than 24x80 text.
The screen-scraping code "scrapes" the data portion from the 3270 output and passes it to the presentation code on the client. When the user keys data or clicks on some feature, the user input is processed and sent to CICS as though the input was prepared on a 3270.
