No, it's not defined in a variable. the reason the suffix is introduced is that it avoids name clashes in the code at compile time. We therefore wont remove the suffix nor make it a configurable element, as it will sooner or later lead to name clashes in the generated code and thus frustration for the user of llblgen pro.
In C# it's a little easier to avoid name clashes as the compiler is smarter, but in VB.NET, it's not easy, as it will for example make mistakes between class references and property names.
You're not the first who asks this, and I'm sure not the last either
. We can't make the change (we tried, it leads to too much problems which pop up after code has been generated).
