You can create as many Procedures worksheets as you want, and each worksheet can contain as many
functions and sub-routines as you want.
To use the Procedures interface:
1. In the Global tab of the Project Explorer, do one of the following:
• To edit the default Procedures worksheet, open the Procedures folder and then double-click Main
Procedures; or
• To create a new Procedures worksheet, right-click the Procedures folder and then click Insert on the
shortcut menu.
Either way, the worksheet is opened for editing.

2. Declare your functions and sub-routines in the interface. For example:
Option Explicit
'Keep the Option Explicit statement in the first line of this interface.
'Procedures with global scope can be implemented here
'Global variables are NOT supported in this interface
Sub MyMessage(message)
MsgBox message, 0
End Sub
Function MyAdd(number1, number2)
MyAdd = number1 + number2
Call MyMessage("The sum is" & MyAdd & ".")
End Function
Note: You can declare local variables within each procedure, but you cannot declare global
variables in this interface. In most cases, you should use tags instead.
