If you're on XP go to:
Start-Programs-Accessories-System Tools-Scheduled Tasks

From there you can run a program to run on a periodic basis.

That program could be Excel, or it could be VBScript, or a bat script.

For starters see what you can do to put DLYPROChdr in an Excel
Auto_Open() Sub.

If you have no control over PROCESS.xls and can't add a Macro to it
then you have to go down the VBScript road.

In VBScript open PROCESS.xls, add your own module, and call a Macro
that calls DLYPROChdr from there.

The VBScript might look like:

Set objXL=Create("Excel.Application")
objXL.Visible=True
oVBC = ojbwb.VBProject.VBComponents
Set M = oVBC.Import("SomeModule.bas")
objwb.Application.Run "SomeModule.DLYPROChdrCallerYouWriteYourself"

tos the VBA that creates headers and footers and instead open a
template that already has to headers and
footer created.
