Hi Jeff,I think you should look at DynamicVariable and ProcessSpecificVariable classes. The first one is a read-only while the second is writable.You have to subclass these class for each variable you want.Ex:DynamicVariable subclass: #MyVar.MyVar value: 4 during: [ MyVar value ]HTH,CamiileOn 15 oct. 2014, at 17:09, J.F.

This seems particularly useful for a web application where you might want to access the request and response from the context. What is the proper name for these kind of variables and where can I read about how to use them?Cheers,
