  2. Removes the duplicates for the fields specified in the SORT FIELDS statement and keeps only the 1st occurence of it

  3. Works only for those records in the i/p file where no duplicates for the fields specified in SORT FIELDS statement,

  4. None of the above

Show answer
Correct Option: B

In the i/p file A contains the records in the following sequence: Arun 20 Naveen40 Priya 35 Naveen10 Priya 25 Arun 50 If the following SORT query runs on file A, how would the o/p file B look like: SORT FIELDS = (1,6,CH,A) SUM FILEDS = (7,2,PD)

technology mainframe

  1. Arun 50 Arun 20 Naveen10 Naveen40 Priya 25 Priya 35

  2. Priya 60 Naveen50 Arun 70

  3. Arun 70 Naveen50 Priya 60

  4. Naveen50 Priya 60 Arun 70

Show answer
Correct Option: B

AI Explanation

To answer this question, we need to understand how the SORT query works and how it will affect the input file sequence.

The SORT query provided has two components: SORT FIELDS and SUM FIELDS.

SORT FIELDS = (1,6,CH,A) specifies that the records should be sorted based on the first 6 characters (position 1 to 6) in ascending order.

SUM FIELDS = (7,2,PD) specifies that the values in the 7th and 8th positions should be summed as they are packed decimal numbers (PD).

Let's go through each option to determine the correct output:

Option A) Arun 50 Arun 20 Naveen10 Naveen40 Priya 25 Priya 35 This option does not seem to be sorted correctly according to the SORT query. Additionally, it does not include the summed values. Therefore, option A is incorrect.

Option B) Priya 60 Naveen50 Arun 70 This option correctly sorts the records based on the first 6 characters and includes the summed values. Therefore, option B is a possible correct answer.

Option C) Arun 70 Naveen50 Priya 60 This option does not seem to be sorted correctly based on the SORT query. Additionally, it does not include the summed values. Therefore, option C is incorrect.

Option D) Naveen50 Priya 60 Arun 70 This option does not seem to be sorted correctly based on the SORT query. Additionally, it does not include the summed values. Therefore, option D is incorrect.

Based on the analysis, the correct answer is option B) Priya 60 Naveen50 Arun 70. This option correctly sorts the records and includes the summed values according to the given SORT query.

In what scenario the sequence field contains the value of 'E' in Sort utility?

How does SUM FIELDS = NONE work?

technology mainframe

  1. Sum up value in the fields specified in the SORT FIELDS statement and keep it as only one occurence in the o/p

  2. Removes the duplicates for the fields specified in the SORT FIELDS statement and keeps only the 1st occurence of it

  3. Works only for those records in the i/p file where no duplicates for the fields specified in SORT FIELDS statement,

  4. None of the above

Show answer
Correct Option: B

In the i/p file A contains the records in the following sequence: Arun 20 Naveen40 Priya 35 Naveen10 Priya 25 Arun 50 If the following SORT query runs on file A, how would the o/p file B look like: SORT FIELDS = (1,6,CH,A) SUM FILEDS = (7,2,PD)

technology mainframe

  1. Arun 50 Arun 20 Naveen10 Naveen40 Priya 25 Priya 35

  2. Priya 60 Naveen50 Arun 70

  3. Arun 70 Naveen50 Priya 60

  4. Naveen50 Priya 60 Arun 70

Show answer
Correct Option: C

AI Explanation

To answer this question, we need to understand the SORT statement in COBOL.

The SORT statement is used to sort records in a file based on specified sort fields. In this case, the SORT statement is:

SORT FIELDS = (1,6,CH,A)
SUM FIELDS = (7,2,PD)

The SORT FIELDS clause specifies the fields to be used for sorting. In this case, it is sorting based on the first 6 characters in ascending order (A). The SUM FIELDS clause specifies the field to be summed, starting from position 7, for a length of 2, and the data type is packed decimal (PD).

Now let's go through each option to understand which one matches the output file B:

Option A) Arun 50 Arun 20 Naveen10 Naveen40 Priya 25 Priya 35 - This option is incorrect because it does not match the sorting and summing criteria specified in the SORT statement.

Option B) Priya 60 Naveen50 Arun 70 - This option is incorrect because it does not match the sorting and summing criteria specified in the SORT statement.

Option C) Arun 70 Naveen50 Priya 60 - This option is correct because it matches the sorting and summing criteria specified in the SORT statement. The records are sorted in ascending order based on the first 6 characters, and the sum of the fields starting from position 7 is calculated.

Option D) Naveen50 Priya 60 Arun 70 - This option is incorrect because it does not match the sorting and summing criteria specified in the SORT statement.

Therefore, the correct answer is option C. The output file B would look like: Arun 70 Naveen50 Priya 60.

How should the SORT statement be used to copy only 10 records with the EMP name 'Anil' to the o/p file, where the Emp name is in the 1st 10 chars of the i/p file?
