What is overflow in qbasic?

In QBASIC, overflow occurs when a calculation produces a result that exceeds the storage capacity of the data type being used. For example, if an integer variable, which can typically hold values from -32,768 to 32,767, exceeds this range during an arithmetic operation, it results in an overflow error. This can lead to unexpected behavior or incorrect results, making it important for programmers to manage data types carefully to avoid such issues.
