Question one hundred thirty. How To Establish Dynamic Cursor Position On A Map? How To Get The Cursor Position When We Receive A Map?
Answer :
We dynamically role a cursor thru an application program the usage of a symbolic call of the symbolic map with the aid of setting -1 into the sphere length (i.E., fieldname + L) of the sector in which you want to location the cursor. The SEND MAP command to be issued have to have the CURSOR alternative (without price). Also, the mapset ought to be coded with MODE = INOUT in the DFHMSD macro. We get the cursor function while we receive a map by checking EIBCPOSN, which is a halfword ( S9(4) COMP) binary field in EIB, and contains offset role (fantastically to zero) of the cursor on the screen.
Question 131. What Are The Three Ways Available For A Program To Position The Cursor On The Screen?
Answer :
Static positioning. Code the insert cursor (IC) in the DFHMDF BMS macro.
. Relative positioning. Code the CURSOR choice with a cost relative to zero (function 1.1 is 0).
Symbolic positioning. Move high values or -1 the sector length within the symbolic map (and code CURSOR on SEND command ).
Question 132. What Is A Mapset?
Answer :
A mapset is a set of BMS maps link-edited together.
Question 133. Why Is A Term Id Recommended In Naming A Tsq?
Answer :
In order to avoid confusion and to keep records security, a strict naming convention for QID will be required inside the installation. Moreover, for a terminal-structured venture (e.G. Pseudo-communique challenge), the terminal identification ought to be protected in QID so one can make certain the individuality of TSQ to the assignment.
Question 134. What Are The Differences Between Temporary Storage Queue (tsq) And Transient Data Quene (tdq)?
Answer :
Temporary Storage Queue names are dynamically defined inside the utility application, at the same time as TDQs should first be described in the DCT (Destination Control Table). When a TDQ carries certain amount of information (Trigger degree), A CICS transaction may be commenced automatically. This does not show up while the use of a TSQ. TDQ (extra partition) can be used by batch utility; TSQ cannot be accessed in batch. The Transient Data Queue is without a doubt a QSAM document. You may additionally replace an current item in a TSQ. A report in a TDQ can't be updated. Records in TSQ may be read randomly. The TDQ may be study simplest sequentially. Records inTemporary Storage may be examine more than once, at the same time as recordes stored in Temporary Data Queues cannot. With TDQs it's miles "one read" most effective.

Question one hundred forty. Explain The Means Of Supporting Pseudo Conversation Programming. (eg. Storing And Restoring Of States, Control Flow, Error Handling)?
Answer :
When we send a map the use of SEND MAP command, Immediately we launch this system by using EXEC CICS RETURN command. In this command we point out the TRANSACTION ID that is to be achieved after receiving the map. In this command we also specify the facts that have to be stored in COMMUNICATION AREA for later use. When this command is performed the corresponding program is released from the memory. After receiving the response from the terminal the program is once more loaded and this time the data which we saved in conversation region could be copied into the operating storage phase. And the map can be acquired with RECEIVE MAP command. The variable EIBCALEN in EIB holds the duration of conversation location. In procedure division we tests the fee of EIBCALEN if it's miles 0, we first ship the map accompanied via RETURN command. Otherwise, this is if EIBCALEN is not zero, we recognize that this transaction is not walking first time and we receive the map by using RECEIVE MAP command.
Question 141. How Can You Start A Cics Transaction Other Than By Keying The Transaction Id At The Terminal?
Answer :

Question 143. What Happens To Resources Supplied To A Transaction When An Xctl Command Is Executed?
Answer :
With an XCTL, the working storage and the system department of this system issuing the XCTL are launched. The I/O regions, the GETMAIN areas, and the chained Linkage Section areas (Commarea from a better stage) stay. All current locks and queues additionally stay in effect. With a LINK, however, application garage is likewise saved, for the reason that transaction expects to go back and use it again.

3. RETURN: To go back to the subsequent higher-stage program or CICS.
Four. LOAD: to load a software
five. RELEASE: To release a software.
Question 151. Explain The Various Ways Data Can Be Passed Between Cics Programs?
Answer :
Data may be exceeded among CICS packages in 3 ways- COMMAREA, TRANSIENT DATA QUEUE $ TEMPORARY STORAGE QUEUE.
Data can be surpassed to a called software the usage of the COMMAREA alternative of the LINK or XCTL command in a calling program. The known as application may alter the statistics content material of COMMAREA and the modifications may be to be had to the calling software after the RETURN command is issued in the referred to as application. This implies that the known as application does not should specify the COMMAREA option in the RETURN command.
