Important Notes & Disclaimer 

This product is developed for educational purposes in COBOL programming. It is provided as a learning tool for programming learners to study COBOL from basics to advanced levels. 

This product is not intended for building or operating business systems. Therefore, our company will not be held responsible for any issues or damages arising from the use of this product in business systems. Please understand this in advance.

Additionally, since this product adopts an interpreter-based approach, the execution performance of programs may be reduced. The interpreter approach involves reading and executing programs line by line, which often results in slower processing speeds compared to the compiler approach.

Furthermore, this product is designed with a philosophy of attempting to run programs as much as possible even in the presence of syntax errors, which may result in unexpected behavior. Therefore, it does not guarantee strict operation or calculation accuracy.

When using this product, please fully understand these points. We continuously strive to improve quality and performance, so please look forward to future updates.
