I don't think it is possible to pass arbitraty parameters on the command line.
You might be able to control calculation in the Workbook+Open event; this
will determine the size (in the filing system) of the workbook being opened:

Sub aa()
Set fsof =
CreateObject("Scripting.FileSystemObject").GetFile (ActiveWorkbook.FullName)
If fsof.Size (20 * 1024) Then
' your code
Else
' your code
End If
Set fsof = Nothing
End Sub

I want to have Excel set up such that when I try to open a file that's
greater than, say, 20 MB, I want the file to open with manual
calculate, else to open normally with automatic calculation. Is there
an easy way to achieve something like this? I tried adding a file to
the XLSTART folder with a macro that checks for file size and according
sets the manual calculation, but I can't get anything like that to work
since I can't pass to this macro the name of the file that was opened
in the first place...
