I am writing a procedure that I want to either access from the macro manager
in the excel interface (without a parameter) or call from another procedure
and pass a parameter. My first inclination was -

Sub ColsHide(Optional CH_Row As Integer = 1)

which would set the CH_Row variable to 1 if not passed as a parameter.
However this approach makes the procedure invisible to the macro manager.

Next approach was to set a public variable in the calling program -

Public CH_Row As Integer

Sub ColsHideKen()

CH_Row = 1
ColsHide

End Sub

but the following code in ColsHide

If VarType(CH_Row) = vbNull Then
CH_Row = Application.InputBox(Prompt:="Enter row number to test",
Title:="COLS HIDE", Default:=1, Type:=1)


Else
' CH_Row already set publicly

End If

works out that CH_Row exists but the following method cannot interpret it as
a valid numeric input

Cells(CH_Row, CH_Col + 1).Select


TIA
