Question: How to convert .bas file to vbscript/exe or running from command line ?
I did script in Excel by MS Visual Basic for Aplications, but i can run this scrip only under Excel. How i can make this script as .vbs or .exe ? ?

Answer: 
I'm afraid that the short answer is that you can't, well at least not directly. VBA and VBS are slight variant's and while you could save the code into a .vbs file I very much doubt that it would do anything without changing it to VB Script.

To make a .exe you will need something like Visual Studio. Even then you would probably need to rework your code to make it do it's job.

I guess it depends on what your code does.
I think everyone has made good points here, but one thing I did not see that would be a big issue is that with VBA and Visual Basic you can use the On Error GoTo command and set an Error line using something such as MainErrorHandler: at the bottom of the function. VB Script does not allow this and you need to use On Error GoTo 0 or On Error Resume next which are both allowed in VBA and Visual Basic. the error handling in VB Script however is allowed in all VB languages.
