Question 1: NATIVE Format Purpose

What is the primary purpose of using NATIVE format in COBOL?

Answer: NATIVE format provides platform-optimized binary representation for maximum computational efficiency. It uses the target system's native format (endianness, alignment, word size) to achieve optimal performance for arithmetic operations and system integration.

Question 2: Performance Benefits

How does NATIVE format improve performance compared to other formats?

Answer: NATIVE format eliminates conversion overhead by storing data in the processor's native format, enables optimal arithmetic operations, provides efficient memory alignment, and maximizes CPU utilization for computational tasks.

Question 3: When to Use NATIVE

In what scenarios should you choose NATIVE over other data formats?

Answer: Use NATIVE for high-performance arithmetic operations, intensive computational tasks, system-level programming, C/C++ interface compatibility, scientific calculations, and when maximum processing speed is critical for the application.
