Save the xla in the XLStart folder & it will be loaded automatically - very
similar tio the personal.xls workbook that many people like to use.
If you have an alternative start up folder - see under Tools/Optios - then
you could put the XLA there instead.
Both these can be used, or indeed, simply use the Add-In Manager -
Tools/Add-Ins

Is an add-in the best way?
