RE: argc argv

 Indeed!

Replace the name of the function.
Instead of your  

> int main(int argc, const char **argv)
use  

void passParameters(const char * par1, const char *par2, ...)  

You can use any other types (int , double, float, ... ) for your parameters too.  

You can do everything in one shot:  

root.exe -q 'passParameters.C+("parameter1","parameter2")'  

Watch 'single' and "double "quotation above.  

Hope this helps, Valeri

But then when I do that I get an error that Error: Function passParameters("parameter1","parameter2") is not defined in current scope

	Probably, you can do the following:
	root[0].L passParameters.cxx
	root[0]passParameters("parameter1","parameter2",....);
	
	cheers,
