I believe this problem was addressed in the 23.9.2017 update of Project
Oberon with a language restriction implemented in ORP.Mod. If you try to
compile the code above you will now get the error message:
"Error: must point to named record"
Follow the practice used throughout Project Oberon i.e. declare your record
as a type and then declare your pointer as a pointer to that type. For
ItemDesc = RECORD c, d: INTEGER END;
a: POINTER TO ItemDesc;
