How to retreive user function and variables list?   

How can we retreive the list of functions and variables in a VBScript
using Script engine?

I have created a project which makes use of Active Script Hosting to
execute dynamic VBScript provided by a user. Can we retreive the list
of functions and variable names sent to the script engine.

For eg:
If the script sent to the VBScript engine is:

Dim gVar1

Function Function1
    MsgBox "ABC"
End Function

Expected output from the sample:
Variables used: gVar1
Functions list: Function1

Thanks in advance.
