Is there a reason for that? In the attached screenshot, the variable outside the do in order can't be assigned any of the variables' values that were declared inside the do in order.

It?s my understanding that if you declare variables within any of the control blocks like while/if/do together - they will be local to that block of code unless declared in the method.

Do in order translation places all instructions inside curly brackets creating a semantic scope.

Message-ID: Nicely illustrated 'technicality'. What's the logic or reason for the inner DoTogether containing only the num1 and nums initializers? Is this exercise only to show the scope doesn't extend outward? AZ On Wed, May 18, 2022 at 1:45 PM Leonel Morales wrote: > I guess it has to do with blocks' translation into Java.

Message-ID: It's hard to find a case where do in order needs to go inside another do in order directly. I have used several consecutive do in order inside a do together, makes sense in some cases. Can't think of a case where the scope of a variable was a problem. Grouping code is another example. If several lines of code have to be copied through the clipboard it is easier to put them all in a do in order block and copy or move it to the clipboard, instead of going line by line. After reorganizing code it may end looking like that for no other purpose than easing copy or move. Not sure. 2022-05-18 13:26 GMT-06:00, Ziccardi, Adam : > Nicely illustrated 'technicality'. > What's the logic or reason for the inner DoTogether containing only the > num1 and nums initializers? > Is this exercise only to show the scope doesn't extend outward? > AZ > > On Wed, May 18, 2022 at 1:45 PM Leonel Morales wrote: > >> I guess it has to do with blocks' translation into Java.
