Data entry

Another good use for a partitioned screen is “heads down” data entry, where the operator's productivity depends on how fast the application can process an input and reopen the keyboard for the next.

With a partitioned screen, you can divide the screen into two identical entry screens. The operator fills one, presses Enter, and then fills the second one while the data entry transaction is processing the first input. If the input is good, the program erases it in preparation for the next entry; if not, there is still an opportunity for the operator to make corrections without losing subsequent work. The CICS 4.1 Sample Applications Guide contains an example of such a data entry transaction.
