I am a new NetLogo user. How do I get the property of sorted turtles?
clear-all
create-turtles 5
foreach (sort turtles) [ask ? [show who]]
However, the above code produces the error below
ERROR: Nothing named ? has been defined.

The syntax of foreach changed with NetLogo 6 and the question mark syntax is no longer supported. The proper syntax is shown at
https://ccl.northwestern.edu/netlogo/docs/dictionary.html#foreach
So, in your case the command would be
foreach (sort turtles) [n -> ask n [show who]]
where "n" is taking on the role of the old "?".
Check out the description of anonymous procedures in the NelLogo dictionary at https://ccl.northwestern.edu/netlogo/docs/dictionary.html#arrow
