Thanks, but lets continue :) In another words, get you method: > function TMyObject.creatObj : TSomeObj; > begin > result := TsomeObject.create; > end; If I have a variable myObj, I can do this: someObj := myObj.createObj; This is the same: someObj := TsomeObject.create; Rigth? But if a remove the variable *someObj* and call like this: myObj.createObj; // I _removed_ the *someObj* here!!! What will happen with the "result" variable? Is it released by the compiler?
