Comp is a binary storage format for integers, while comp3 is a packed decimal storage format.

• Comp variables are stored in binary format, taking up less space than comp3 variables.

• Comp3 variables are stored in packed decimal format, allowing for easier decimal arithmetic operations.

• Comp variables are more efficient for arithmetic operations, while comp3 variables are easier to read and understand.

• Example: comp variable - 1234, comp3 variable - 1234.

Evaluate statement is important in COBOL for conditional processing and decision making.

• Used to compare values and execute specific statements based on conditions
