I had to put a $get

[driftingprogrammer]

While playing around and trying to use the iterate function with the global ^Settings on https://gettingstarted.intersystems.com/language-quickstarts/objectscript-quickstart/ I was getting an error, and using the $get function on line 20 fixed it for me. Would it not be a good practise to use the $get function on line 20 of ObjectScript.cls anyways.

Thanks.

Thanks for bringing this up. The current code sample is meant as a simple illustration, but indeed you can trip over this error if there is an additional subscript (which dwells just a little outside of the sample scenario).

Assigning to @isc-mlo who owns this part of the documentation for his consideration.

To other developers that are learning ObjectScript and reading this: we don't want to teach anyone to "use the $get function everywhere, just to be safe." In this QuickStart:

• Using $get is not necessary when calling the Iterate() method as it is written, since it's looping through ^testglobal..
• Changing Iterate() to loop through the ^Settings global is a fine thing to try. Typically, a global with multiple levels of subscripts would be traversed using nested $order loops, one per level (which as @bdeboe said, is beyond the focus of this QuickStart). When looping through only the first level of ^Settings, using $get will prevent the <UNDEFINED> error for the "Auto1" and "Auto2" subscripts. Or, do the following in the Web Terminal and run Iterate() without the $get:
  set ^Settings("Auto1") = "Mustang", ^Settings("Auto2") = "Charger"
