I've got a routine that works in Excel version 10 but does not in Excel
version 9. The glitch is apparently in a call statement I'm making. What I'm
using looks like...

Sub Routine02 ()
Dim stuff as whatever
Get stuff
Call Routine03(ThisSheet, RNumRows, RFirstRowNum, LastRowNum,RFirstColNum,
RNumCol, OutputRow, OutputCol)
End Sub

Sub Routine03 (ThisSheet, RNumRows, RFirstRowNum, RLastRowNum,RFirstColNum,
RNumCol, OutputRow, OutputCol)

Do stuff
End Sub

Obviously version 10 is more forgiving of sloppy programming. Can anyone
tell me what I'm doing incorrectly?

Thanks in advance,
Raul
