How to work with return values in macro?

[AAM71]

Hi All,

How to work with return values in macro? For example, File.delete(path) returns 1 if delete is successful. Then how I can get access to this return value?
Sorry for a stupid question.

Best regards,
Alex

Dear Alex,
just do:
value = File.delete(path);
print(value);
That's it!
My best regards,
Philippe

Greetings Alex,

you could test if the operation was successful and decide what to do if yes
or no, e.g.

// ... some code ...
if ( File.delete(path) ) {
    // ... do something ...
} else
    exit("File could not be deleted.");
//

You may also ignore the return value.
