  1. It is correct.

  2. It is not correct because first-name and middle name contain the same PIC Clauses

  3. Not correct because the PIC Clause is missing for the first three data items.

  4. Not correct because the level number 03 is missing

What is the difference between comp and comp-3 usage.
technology mainframe

  1. Comp is binary usage, while comp-3 indicates packed decimal.

  2. Comp is a packed decimal, while comp-3 indicates binary usage.

  3. Comp and Comp-3 are packed decimal.

  4. Comp and Comp-3 are binary usage.

Show answer
Correct Option: A
Explanation:

To understand the difference between comp and comp-3 usage, the user needs to know about the different data types in COBOL programming language.

A) Comp is binary usage, while comp-3 indicates packed decimal. This option is incorrect because comp is not binary usage. Comp is a usage for binary integers and comp-3 is a usage for packed decimal.

B) Comp is a packed decimal, while comp-3 indicates binary usage. This option is incorrect because it incorrectly states the usages of comp and comp-3. Comp is a usage for binary integers, while comp-3 is a usage for packed decimal.

C) Comp and Comp-3 are packed decimal. This option is incorrect because comp and comp-3 are not both packed decimal. Comp is a usage for binary integers, while comp-3 is a usage for packed decimal.

D) Comp and Comp-3 are binary usage. This option is incorrect because comp and comp-3 are not both binary usage. Comp is a usage for binary integers, while comp-3 is a usage for packed decimal.

The Answer is: A. Comp is binary usage, while comp-3 indicates packed decimal.

01 WS-TOP PIC X(1) 01 WS-TOP-RED REDEFINES WS-TOP PIC X(2). If you MOVE "12" to WS-TOP-RED, DISPLAY WS-TOP will show

  4. 121

Show answer
Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of REDEFINES in COBOL.

In COBOL, the REDEFINES clause is used to define two or more data items that occupy the same storage location. Essentially, it allows you to define different data items that share the same memory space.

In this case, we have two data items:

  1. WS-TOP: This is defined as a single character element.
  2. WS-TOP-RED: This is defined as a redefinition of WS-TOP, but with a length of 2 characters.

When you MOVE "12" to WS-TOP-RED, it means that you are assigning the value "12" to the memory space occupied by WS-TOP-RED. Since WS-TOP-RED redefines WS-TOP, both data items share the same memory space.

Now, when you DISPLAY WS-TOP, it will show the value stored in the memory space occupied by WS-TOP. Since "12" was moved to WS-TOP-RED, which redefines WS-TOP, the value displayed will be the first character of the moved value, which is "1".

Therefore, the correct answer is B) 1.
