void plot(Char_t *fname)
{
  printf("%s\n",fname);
}
and
root [0] .x plot.C("test");
test
NULL
root [1] 
works but with different parameter:
root [1] .x plot.C("test.root");
Syntax error: G__getexpr: Parenthesis or quotation unmatch plot.C("test() 
FILE: LINE:0
NULL
root [2] 
where is the problem ?
