Do you remember MS DOS?

We all remember DOS was the king back in the 80's I try to open an Excel files thru the attached batch file but it opens the excel program and then it stops. Anyone remembers what is the right syntax to open the "Summary.xls" file? Instead of "open" I did try "start" and "run" with no success @ECHO OFF cd c:\program files (x86)\microsoft office\office10\excel.exe start excel.exe
