JCL and XML Programming Languages Quiz

In-stream data is terminated with /* in JCL. This delimiter marks the end of data following a SYSIN * or SYSUT1 * DD statement. // starts JCL statements, //* is for comments, and //** is not valid JCL syntax.

In XML, all elements must be properly closed, either with an end tag or as self-closing elements. This is different from HTML where some elements don't require closing tags. XML's strict well-formedness rules require all elements to be closed.

SYSUT2 is the standard DD (Data Definition) name used in JCL utility programs to specify the output file. The convention pairs SYSUT1 (input) with SYSUT2 (output) for utilities like IEBCOPY, IEBGENER, and SORT. Option A is incorrect because SYSUT1, not SYSUT2, identifies the input file.

The SORT FIELDS syntax requires: starting position (column), length of field, format (CH, BI, FI, etc.), and sort sequence (A for ascending, D for descending). Option B correctly lists all four parameters in the right order. Options A and C incorrectly include 'end-location' instead of 'length', while option D has the wrong order.

XML tags are case-sensitive, meaning , , and are treated as three different tags. This is a fundamental XML rule designed to prevent ambiguity. The statement claims tags are NOT case-sensitive, which is false.

In JCL, comment statements must begin with //* in columns 1-3. The //* sequence uniquely identifies the line as a comment. Option A (//) is used for JCL statements but not comments, while option C (/*) is used in some programming languages but not JCL.

XML element names must follow specific naming rules: they can contain letters, digits, hyphens, underscores, and periods; must start with a letter or underscore; cannot contain spaces; and cannot begin with 'xml' in any case combination. These rules ensure XML parsers can reliably process documents.

XML attribute values MUST be enclosed in quotes. The correct syntax is or . Unquoted attribute values like 'sex=female' make the XML malformed and parsers will reject it. Quotes are mandatory for all attribute values.

XML attributes cannot contain multiple values in a single attribute. Each attribute can hold only one value. To store multiple values, you must either use multiple attributes (e.g., which is invalid) or, properly, use separate elements or repeat the child element.

To solve this question, the user needs to know about how to restart an abnormally terminated job.

Option A: Specify RESTART = STEPNAME in the JOB step.

This option is partially correct. In order to restart an abnormally terminated job, the RESTART parameter must be specified in the JOB statement. However, the value for RESTART should be the name of the step where the job should resume, not "STEPNAME".

Option B: Specify RESTART = Y in the JOB step.

This option is incorrect. There is no value of "Y" for the RESTART parameter. The valid values are the step name where the job should restart or "RESTART=NO" to prevent a job from being restarted.

Option C: Specify RESTART = N in the JOB step.

This option is incorrect. "N" is not a valid value for the RESTART parameter. The valid values are the step name where the job should restart or "RESTART=NO" to prevent a job from being restarted.

Option D: None of the above.

This option is incorrect. Option A is partially correct, but the other options are incorrect.

Option E: All of the above.

This option is incorrect. Option A is partially correct, but the other options are incorrect.

Therefore, the correct answer is:

The Answer is: A. Specify RESTART = STEPNAME in the JOB step.

There's a distinction between 'well-formed' XML (correct syntax) and 'valid' XML (well-formed + conforms to DTD/schema). A document can be well-formed without being validated against a DTD. Validating against a DTD makes it 'valid' XML, not just 'well-formed' - it must already be well-formed to even be validated.

XML parsers are strict by design - they halt execution when encountering any syntax error (malformed XML). Unlike HTML browsers that tolerate errors, XML applications will not process malformed documents. This strictness ensures reliable data exchange between systems.

CSS can be applied to XML documents to control display, formatting, and presentation. This is commonly done by linking a stylesheet using the processing instruction. CSS styles XML elements by tag name, allowing XML data to be rendered visually in web browsers or other applications.

To answer this question, the user needs to know about DD statements and their purpose. DD (Dataset Definition) statements are used to define and allocate datasets in JCL (Job Control Language) for use by a job step.

The correct answer is option B.

Explanation:

The DD statement used to supply the name of a dataset is the Dsname parameter. This parameter specifies the name of the dataset being allocated or accessed by a job step.

Option A (Name) is not a valid parameter in a DD statement.

Option C (Label) is used to specify a label for a dataset.

Option D (File) is also not a valid parameter in a DD statement.

Option E (None of the above) is incorrect because option B (Dsname) is the correct answer.

Therefore, the answer is: B.

The NOTIFY parameter in JCL's JOB statement allows you to specify a TSO user ID to receive a message when the job completes. The syntax is NOTIFY=userid. Options STATUS, ENDMSG, and USER are not valid JCL parameters for this purpose. NOTIFY is the correct and standard mechanism.

Symbolic parameters (e.g., &VAR) are used in JCL procedures to allow flexibility. They can be used to override DD statement parameters and assign values to common JCL settings, making procedures reusable across different environments.

IEBGENER is the standard IBM utility for copying sequential datasets or converting them to different formats. IEBCOPY is specifically for partitioned datasets (PDS/PDSE), and IEFBR14 is a dummy program used to allocate or delete datasets via JCL.

To solve this question, the user needs to know about JCL (Job Control Language) and the different parameters that can be used to customize a job step.

The JOBLIB and STEPLIB parameters are used to specify the location of program libraries that contain the executable programs required for a job. The PGM parameter is used to specify the name of the program to be executed for a particular job step.

Option A - JOBLIB: The JOBLIB parameter is used to specify the location of program libraries that contain the executable programs required for the entire job. This parameter is not specific to a particular job step.

Option B - STEPLIB: The STEPLIB parameter is used to specify the location of program libraries that contain the executable programs required for a particular job step. This option is correct as it provides a way to specify the location of the program specific to a job step.

Option C - Any of the above: This option is incorrect as the JOBLIB parameter cannot be used to specify the location of the program for a specific job step.

Option D - PGM: The PGM parameter is used to specify the name of the program to be executed for a particular job step. This parameter does not specify the location of the program.

Therefore, the correct answer is:

The Answer is: B. STEPLIB

To answer this question, the user needs to know about the SPACE parameter used in JCL and its sub-parameters.

Now, let's go through each option and explain why it is right or wrong:

A. Specifies storage space for recording of name and location of partitioned datasets: This option is incorrect. The SECONDARY sub-parameter specifies the amount of additional space required if the originally specified space is insufficient. It does not relate to the recording of name and location of partitioned datasets.

B. Specifies additional storage space if the originally specified space is insufficient: This option is correct. The SECONDARY sub-parameter specifies the amount of additional space required if the originally specified space is insufficient.

C. Specifies storage space at the time the dataset is created: This option is incorrect. The SPACE parameter specifies the primary space allocation required for a dataset at the time of creation. The SECONDARY sub-parameter specifies the amount of additional space required if the originally specified space is insufficient.

D. Specifies the space required in cylinder: This option is incorrect. The SPACE parameter specifies the primary space allocation in terms of tracks, cylinders, or blocks for a dataset. The SECONDARY sub-parameter specifies the amount of additional space required if the originally specified space is insufficient.

Therefore, the correct answer is:

The Answer is: B

To solve this question, the user needs to know about JCL (Job Control Language) and the concept of procedures.

The correct answer is:

A. Procedure or PROC

Explanation:

In JCL, a procedure is a set of JCL statements that are grouped together and given a name. This name is called a PROC and it can be used throughout the JCL code instead of writing the same block of code multiple times. Procedures can be defined either within the JCL job itself or in a separate member of a partitioned dataset called a procedure library.

Cataloged Procedures (option B) are a specific type of procedure that are stored in a system library and can be invoked from any job in the system. In-stream Procedure (option C) is a term used to refer to a procedure that is defined within the JCL job itself, rather than in a separate member of a partitioned dataset.

Option D is incorrect as option A is the correct answer.

Therefore, the answer is: A. Procedure or PROC
