4DEVAL is designed for expressions that may or may not return a value.
OB Get always returns a value,
so it more natural to use 4DTEXT or 4DHTML.
but I guess you meant something like
<!--#4DEVAL $key:=OB Get(jsonObj;"key";Is longint)-->
*
as for iterating over elements of an array,
you can obtain the array with 4DEVAL+OB GET ARRAY,
and pass that local array to 4DLOOP.
you can also embed many lines of 4D code with 4DCODE (15r4).
having said that, I agree with Tom D,
it's better to decouple the data from the page and use AJAX instead.
