When using the PERFORM statement in COBOL, what is the difference between PERFORM...THRU and PERFORM...UNTIL?
- PERFORM...THRU is used for conditional statements, and PERFORM...UNTIL is used for unconditional statements.
- PERFORM...THRU is used for looping, and PERFORM...UNTIL is used for sequential execution.
- PERFORM...THRU is used with arrays, and PERFORM...UNTIL is used with strings.
- PERFORM...THRU specifies a range of paragraphs to be executed, while PERFORM...UNTIL repeats execution until a specified condition is true.
PERFORM...THRU is used to specify a range of paragraphs to be executed sequentially, while PERFORM...UNTIL repeats the execution until a specified condition is true. Understanding the difference is crucial for effective use of the PERFORM statement in COBOL programs.
