Conditionally Compile Your Code

Most developers know about VB4's Conditional Compilation feature, where you can declare Windows APIs for 16-bit and 32-bit operating systems:
#If Win#32 then
        'If running in 32-bit OS  
        Declare SomeApi....
        'If running in 16-bit OS
        Declare SomeApi
#End IF 
This same feature applies not only to Windows API statements, but also to your own functions:
#If Win32 Then
        Dim lRc&
        lRc& = ReturnSomeNumber(35000)
        Dim lRc%
        lRc% = ReturnSomeNumber(30000)
#End If

#If Win32 Then
        Private Function ReturnSomeNumber_
                (lVar&) As Long
                ReturnSomeNumber = 399999
        Private Function ReturnSomeNumber_
                (lVar%) As Integer
                ReturnSomeNumber = 30000
#End If

End Function
