trymethod(2,0) will give One Three four trymethod(3,0) will give One Two Four Five >> The retry statement can be written only in a catch block. The retry statement causes control to jump up to the first line of code in the associated try block. The retry statement is used when the cause of the exception can be fixed by the code in the catch block. The retry statement gives the code in the try block another opportunity to succeed. The retry statement erases all messages that have been written to the Infolog since program control entered the try block.

agreed. In Dynamics 365 Finance and Supply Chain Management, when using X++ with a try-catch-finally statement, a return statement inside the catch block will cause the method to exit and return the specified value or expression, but the finally block will still execute before the method fully exits.

tryMethod(3,0) → One, Two, Four, Five (The retry statement erases all messages that have been written to the Infolog since program control entered the try block.) - this output will be visible in the D365 application - but in the Infolog of Visual Studio will be - One Three One Two Four Five
