Correct Option: A

AI Explanation

To answer this question, you need to have an understanding of the COBOL II programming language.

In COBOL II, the maximum size of a 01 level item is determined by the PIC clause. The PIC clause defines the data type and length of the item.

The PIC X clause is used to define alphanumeric data. Each character occupies one byte of storage. Therefore, the maximum size of a 01 level item defined with PIC X is determined by the maximum number of bytes that can be allocated for a single item.

In COBOL II, the maximum number of bytes that can be allocated for a single item is 16,777,215 bytes. This corresponds to option A.

Let's go through each option to understand why they are correct or incorrect:

Option A) 16777215 - This option is correct because it represents the maximum number of bytes that can be allocated for a 01 level item in COBOL II.

Option B) 16777200 - This option is incorrect because it does not represent the maximum number of bytes that can be allocated for a 01 level item in COBOL II.

Option C) 1677250 - This option is incorrect because it does not represent the maximum number of bytes that can be allocated for a 01 level item in COBOL II.

Option D) 16772150 - This option is incorrect because it does not represent the maximum number of bytes that can be allocated for a 01 level item in COBOL II.

The correct answer is option A. This option is correct because it represents the maximum size of a 01 level item in COBOL II.

Sample Code Field in working storage: 05 S-EOF-CHECK PIC X(01). 88 S-NOT-END-OF-FILE VALUE 'N'. 88 S-END-OF-FILE VALUE 'Y'. MAINLINE. SET S-END-OF-FILE TO TRUE PERFORM A0100-PRINT-DETAIL-AND-FOOTERS UNTIL S-END-OF-FILE END-PERFORM. Using the sample working storage and mainline section of a program, which one of the following is the coding error that occurred in the sample above?

technology mainframe

  1. A READ statement is missing in the MAINLINE section after the PERFORM.

  2. MAINLINE must not contain any statements other than the PERFORM statement.

  3. S-EOF-CHECK is not properly initialized prior to the PERFORM statement

  4. The line "SET S-END-OF-FILE TO TRUE" is not a valid statement.

  5. In working storage, an 88 level must be defined for values of S-EOF-CHECK other than 'N' and 'Y'.
