To answer this question, we need to understand the concept of file status codes in COBOL.
File status codes are used to indicate the status of a file operation in COBOL programs. Each file operation, such as opening, reading, writing, or closing a file, can result in a specific file status code being returned.
In this case, file status 39 indicates a mismatch between the attributes of a file specified in the COBOL program and the attributes specified in the JCL (Job Control Language) used to execute the program.
Let's go through each option to understand why it is correct or incorrect:
Option A) Mismatch in LRECL between your COBOL pgm & the JCL - This option is incorrect because file status 39 specifically indicates a mismatch in attributes but does not specify LRECL (Logical Record Length) as the cause.
Option B) Mismatch in BLOCKSIZE between your COBOL pgm & the JCL - This option is incorrect because file status 39 does not specifically indicate a mismatch in BLOCKSIZE.
Option C) Mismatch in RECFM between your COBOL pgm & the JCL - This option is incorrect because file status 39 does not specifically indicate a mismatch in RECFM (Record Format).
Option D) All of the above - This option is correct because file status 39 can occur when there is a mismatch in any of the attributes mentioned in options A, B, or C. Therefore, this is the correct answer.
The correct answer is D) All of the above. This option is correct because file status 39 indicates a mismatch in attributes between the COBOL program and the JCL, which can include LRECL, BLOCKSIZE, or RECFM.
