SYMPTOMS
========

Script code runs when you load code into the script control using the AddCode
method.

CAUSE
=====

The script contains statements outside of a procedure definition.

RESOLUTION
==========

Remove any statements outside of procedure definitions.

STATUS
======

This behavior is by design.

MORE INFORMATION
================

With Active Scripting, unlike Visual Basic and most other languages, statements
are allowed outside procedure definitions. This is to allow the script to
automatically initialize itself at load time.

demonstrated and the tools used to create and debug procedures.

Steps to Reproduce Behavior
---------------------------

1. In Visual Basic, create a new project (Form1 is created by default).

2. Click Components on the Project menu, and then select the "Microsoft Script
  Control 1.0" check box.

3. Add the Script control (ScriptControl1), a text box (Text1), and a command
  button (Command1) to a form. Set the MultiLine property of the text box to
  TRUE. For ease of use, change the size of Text1 so that it accommodates 5
  lines of 60 characters.

4. Add the following code to Form1:

        Private Sub Command1_Click()
          On Error Resume Next
          With ScriptControl1
            .Language = "VBScript"
            .AllowUI = True
            .AddCode Text1.Text
          End With
        End Sub

5. Run Form1 and open the Debug window.

6. Type the following script in the text box:

        Sub Test()
          MsgBox "Hello World"
        End Sub
        Test

7. Click the command button. The message box appears.

8. Remove the line "Test" from the script and run Form1 again. The Test code is
  not executed upon loading the code.
