many start commands batch in the same window

I would like to start 3 commands in the same window.

For now I have this batch but there are 3 different windows at each command.

start /d "c:\Program Files\myfolder" cmd /k cscript A 
timeout /t 6 >nul
start /d "c:\Program Files\myfolder" cmd /k cscript B
timeout /t 6 >nul
start /wait /d "c:\PProgram Files\myfolder" cmd /k cscript C

What should I modify to have only one window? thanks
