Accepted Answer

Answering questions related to COBOL, SORT utility, and file usage.

1) Redefines are used in COBOL to allow multiple data items to occupy the same storage space.
2) The order of processing in a SORT statement is: Copy, Include, Omit, Sort.
3) Looping in COBOL can be achieved using PERFORM or EVALUATE statements.
4) The structure of COBOL consists of divisions, sections, paragraphs, and sentences.
5) SORT DD Statements in SORT utility define the input and output files for sorting, SORTWRK is used for temporary storage.
6) Types of data in SORT fields include character, numeric, and date. Zoned decimal and packed decimal are numeric data types with different storage formats.
7) A cursor is used to retrieve and manipulate rows in a database. Its structure includes declaration, opening, fetching, and closing.
8) Files in COBOL are used for input/output operations. Steps include file declaration, opening, reading/writing, and closing.
9) Different modes of access in COBOL include sequential, random, and dynamic.
10) File optimization aims to improve the efficiency of file processing. It can be achieved through techniques like indexing and buffering.
11) SORT and Syncsort are both sorting utilities, but they may have differences in features and syntax.
