SMNP language doesn't have any sophisticated error handling mechanism, however, you are still able to raise errors using throw statement. The throw construction is inspired by Java language, however instead of throwing exceptions SMNP language allows you only to throw string values. When control flow meet throw statement, program execution is immediately interrupted and Execution Error is raised with message passed to throw statement.

Example:

function divide(a: int, b: int) {
    if (b == 0) {
        throw "You are trying to divide by 0!";
    }

    return a / b;
}

If you try to invoke e.g. divide(2, 0) the following error will be raised:

Error
Source: /.../.../scratchpad.mus
Position: line 10, column 15

You are trying to divide by 0!

Stack trace:
[1] <root>::divide(int, int)
[0] <root>::<entrypoint>()

SMNP language does not support any equivalent of try-catch statements known from other languages. Because the SMNP is not aimed at building complex systems and there is simply no need to implement sophisticated error handling system in simple music, you are actually unable to implement more advanced multi-layer error handling system.
