How can I use Lotus 123 comands?; can I format Excel to do so?

I was able to use the 'transition' app when I was using Excel 2000, but I
would like to continue to use the Lotus 1-2-3 commands,, formulas, etc. while
using Excel 2007 and the Beta version of Excel 2010...

Please help as soon as possible...

Thank you very much...
