Why is this an issue?
A long parameter list can indicate that a new structure should be created to wrap the numerous parameters or that the procedure is doing too many
things.
Noncompliant code example
With a maximum number of 3 parameters:
Public Sub Foo(ByVal p1 As Integer, ByVal p2 As Integer, ByVal p3 As Integer, ByVal p4 As Integer) ' Noncompliant
' ...
End Sub
Public Function Bar(ByVal p1 As Integer, ByVal p2 As Integer, ByVal p3 As Integer, ByVal p4 As Integer) ' Noncompliant
' ...
End Function
Compliant solution
Public Sub Foo(ByVal p1 As Integer, ByVal p2 As Integer, ByVal p3 As Integer)
' ...
End Sub
Public Function Bar(ByVal p1 As Integer, ByVal p2 As Integer, ByVal p3 As Integer)
' ...
End Function
