Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of a symbolic map.

Option A) A link edit map - This option is incorrect because a link edit map is used during the linking process to resolve symbolic references between program modules.

Option B) A map of all the entry points in the CICS region - This option is incorrect because a symbolic map is not related to the entry points in a CICS region.

Option C) A copybook member that is included into the source. It contains code defining the fields on the map - This option is correct. A symbolic map is a copybook member that is included in the source code. It contains code defining the fields on the map, such as the field names, lengths, and types.

Option D) The load module that is loaded into the CICS region when a program sends a map - This option is incorrect because a symbolic map is not the load module that is loaded into the CICS region. It is a copybook member used during the source code compilation.

The correct answer is C) A copybook member that is included into the source. It contains code defining the fields on the map. This option is correct because it accurately describes what a symbolic map is.

The difference between a LINK and a XCTL is:

technology mainframe

  1. The LINK is always more efficient than the XCTL.

  2. LINK returns to the calling program and XCTL will not.

  3. The LINK is not available in the current CICS version.

  4. Link cannot pass values to a subroutine.

Show answer
Correct Option: B

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) The LINK is always more efficient than the XCTL. - This option is incorrect. The efficiency of LINK and XCTL depends on the specific scenario and requirements. Both LINK and XCTL have their own advantages and disadvantages, and the choice between them depends on the specific use case.

Option B) LINK returns to the calling program and XCTL will not. - This option is correct. The key difference between LINK and XCTL is that LINK allows the control to return to the calling program after executing the called program or subroutine, while XCTL does not return control to the calling program. After executing XCTL, the control is transferred directly to the called program or subroutine.

Option C) The LINK is not available in the current CICS version. - This option is incorrect. LINK is a standard CICS command and is available in all versions of CICS.

Option D) Link cannot pass values to a subroutine. - This option is incorrect. LINK can pass values to a subroutine using the COMMAREA parameter. The COMMAREA is a data area that can be used to pass data between programs during a LINK operation.

The correct answer is B. LINK returns to the calling program and XCTL will not.
