2/20/2023 0 Comments Cics ceda define program![]() They are similar to batch programs that run in the batch mode. ![]() All the necessary inputs are provided when the program is started. While executing non-Conversational programs, no human intervention is required. Pseudo-Conversational Programs - We will discuss in the next module. ![]() It contains Return code of the last transactionĬICS Programs are classified in the following three categories which we will discuss one by one − The following table provides a list of fields which are present in EIB − EIB Field The data in EIB at runtime can be viewed by executing the program in CEDF mode. It contains information about transaction identifier, time, date, etc., which is used by the CICS during the execution of an application program.Įvery program that executes as a part of the task has access to the same EIB. ![]() It contains a set of system related information corresponding to the task. The EIB is unique to a task and it exists for the duration of the task. All file I/O in CICS is handled by the file control module and they have their own set of statements like READ, WRITE, REWRITE, and DELETE which we will be discussing in the upcoming modules.įile Section and Environment Division is not required.ĬOBOL statements that invoke operating system functions like Accept, Date/Time cannot be used.ĭo not use DISPLAY, MERGE, STOP RUN, and GO BACK.Įxecute Interface Block (EIB) is a control block which is loaded automatically by the CICS for every program. Following are the COBOL verbs which should not be used in a CICS program −įile I/O statements like Open, Read, Write, Rewrite, Close, Delete, and Start. If we code these COBOL verbs, it will not give any compilation error, but we may get unpredictable results. ![]() While coding a CICS program, we cannot use the commands which return the control directly to the MVS. EIB contains the information required during the execution of a program. EIB (Execute Interface Block) acts as an interface to allow application programs communicate with the CICS. Any application program would require an interface to interact with the CICS. ![]()
