RE: [ROOT] main(int argc, char **argv) - Syntax in macros

Yes,
  If your macro defines some "subroutine" let say MyTest and the name of
the file match the name of the subroutine:

MyTest(char *letters, int number){
 . . . 
}

  then you can call it

>root 'MyTest.C("mytest",34)'

etc.

see: ftp://root.cern.ch/root/Users_Guide_3_2c.pdf, page 93.
(it seems to me it does miss to mention one can start ROOT macro from
the shell directly)

On other hand you can use TApplication::Argc(),TApplication::Argv()
to provide your custom action as well.
(see: http://root.cern.ch/root/htmldoc/TApplication.html )

Hope this helps, Valeri
