Hello
 
  In Eval we have to pass a collection always with all variables needed to unknow symbols ??

  1) Does Eval get all Sub  or Function local vars automatically ? (Declared variables and parameters)
  2) Is there a way to do it ?
 
  I tried to run an Eval inside  a Sub refering to a local variable and it didn't get the local variable. Throwed a Unknown Symbol error.

  Eval is used mostly to facilitate this concatenation with "local" or "scope" variables…

 Eval only sees global Public variables.

Variables local to a Sub / Function (with Dim) are private to that function so must be added to the context collection.

For Public variables local to the same class you must use the class name.

eg.
In a class called FMain.class

For Private variables you will also need to use the context Collection
