pharo creating a global variable like transcript

Question

I want to create a variable named MameGap which is accessible from every where. I can print some words to transcript for ex. from a method of a class. I want to do this for MameGap too.

I tried something like this

MameGap:= MyClass new.
Smalltalk at: #myMap put: MameGap.

I want to access MameGap like this

doSomething: aVar
   |x|
   x:= MameGap getInt.
   ^x*3

You have to do:

Smalltalk at: #MameGap put: MyClass new

also you can put there just a class object, like

 Smalltalk at: #MameGap put: MyClass

and sen to it class-side messages
