Hi, i work with Pharo and GLASS. My question is relative to reference method variable define in the method. If i have methodA: methodA | var1 | var1 := 'this is an string'. self methodB. and methodB: methodB | a b c | a := 'a'. ......... i can now at this step reference the var1 defined in methodA ? I think it's in the stack or i wrong ? It's no elegant do it ? a need call self methodB: var1 The question is because i have some class for manage database and i will don't add istances variable to manage the operations on it. With this reference i can solve the problem without pass variables from some methods to other methods. If i found in the stack the specific reference i can manage some operations based on it. Any other indications to solve this problematic ? Thanks, Dario
