In the ISPF Edit panel, there are fields named PROJECT, GROUP, TYPE, and MEMBER. What information do these fields specify?

technology mainframe

  1. DSNAME

  2. DDNAME

  3. PARM field

  4. DD Statement

Show answer
Correct Option: A

AI Explanation

To answer this question, let's go through each option and understand what information these fields specify:

Option A) DSNAME - This option is the correct answer. In the ISPF Edit panel, the PROJECT, GROUP, TYPE, and MEMBER fields specify the DSNAME (data set name) of the dataset or member you want to edit.

Option B) DDNAME - This option is incorrect. The DDNAME field is used in JCL (Job Control Language) to identify a specific DD (data definition) statement.

Option C) PARM field - This option is incorrect. The PARM field is used in JCL to pass parameters to a program or utility.

Option D) DD Statement - This option is incorrect. The DD Statement is a JCL statement used to define the input, output, or control data sets for a job step.

The correct answer is Option A) DSNAME. This option is correct because the PROJECT, GROUP, TYPE, and MEMBER fields in the ISPF Edit panel specify the DSNAME (data set name) of the dataset or member you want to edit.

If a userid is ZTEST1, then what is entered in the Data Set List Utility (generally option 3.4) for "Dsname Level" to list all data sets with the high level qualifier of the userid?

technology mainframe

  1. ZTEST1

  2. "ZTEST1"

  3. .ZTEST1

  4. 'ZTEST1*'

Show answer
Correct Option: A

AI Explanation

To answer this question, we need to understand how the "Dsname Level" works in the Data Set List Utility.

The "Dsname Level" is used to specify the high-level qualifier of the dataset that you want to list. In this case, we want to list all datasets with the high-level qualifier of the userid "ZTEST1".

Option A) ZTEST1 - This option is correct. By entering "ZTEST1" in the "Dsname Level" field, you are specifying the high-level qualifier as "ZTEST1", which will list all datasets with that high-level qualifier.

Option B) "ZTEST1" - This option is incorrect. The double quotes around "ZTEST1" are not necessary and will not work in the "Dsname Level" field.

Option C) .ZTEST1 - This option is incorrect. The asterisks (*) are used as wildcards in dataset names, but they should not be used in the "Dsname Level" field. They can be used to specify patterns for the dataset name, but not for the high-level qualifier.

Option D) 'ZTEST1*' - This option is incorrect. The single quotes around 'ZTEST1*' are not necessary and will not work in the "Dsname Level" field.

Therefore, the correct answer is A) ZTEST1.

PC keyboards do not have a "PA1" key, 3270 emulators map some keys to "PA1". What is the "PA1" key used for in TSO and ISPF?

technology mainframe

  1. Terminate the program currently running.

  2. Terminate ISPF to return to the TSO READY prompt.

  3. Pause a program so that data will not continue to scroll.

  4. Clear the screen to allow the next screen of data to display.

Correct Option: A

The syntax: //INPUT DD * is used for what purpose?

technology mainframe

  1. To specify that this DDNAME refers to a null dataset

  2. To specify that this DDNAME refers to the same dataset as the prior DD statement

  3. To specify that the data is contained in the JCL stream immediately after this DD statement

  4. To specify that the DDNAME refers to the same dataset as the DD statement with DDNAME of INPUT in the prior job step

Show answer
Correct Option: C

What is the relationship of the Layered Network Models of TCP/IP, OSI, and SNA?

technology mainframe

  1. SNA is an internal construction in z/OS and does not allow for end points.

  2. They are the same except that the OSI model inverts the layers top to bottom.

  3. They have the same layers with the exact same functions in each layer, but the names are different.

  4. The layers are conceptually similar but differ in name and details of what functions are in which layers.
