What is the purpose of DPS 2200?
-
It helps to run a batch program.
-
It is used to write the application programs.
-
It helps to access the database.
-
It helps to create the forms and its run-time system communicates with application program.
DPS 2200 is a forms development and runtime system. Its primary purpose is to help developers create forms for mainframe applications, and its runtime system handles communication between the forms interface and the underlying application programs. It's not primarily for batch processing, writing application code, or direct database access.
DPS 2200 refers to a screen/forms-definition facility historically associated with Unisys (Sperry) mainframe environments, used to design data-entry forms/screens whose run-time component then interfaces with the application program to pass field data back and forth during transaction processing. That matches the marked answer: it 'helps to create the forms and its run-time system communicates with application program.' The distractors describe unrelated functions — running batch programs, writing application code, and accessing the database — which are handled by other subsystems, not DPS 2200's forms-definition role.
