Hi, Rooters,

I have three questions:

1. I basicly can follow the example to call CERNLIB routines,
but now I am dealing with complex type in fortran, for example
complex*16 wwerf(Z), and I am wondering how should I declare
wwerf in CERNfunctions.h.

2. I have a class which has member functions in the format like
Double_t myclass::funcs(Double_t *x,Double_t *par), I want to
have a methord to draw this function, but since it is not
pure function, how can I acheive this?

3. Can I include a picture, for example in gif format, in an
existing canvas?

Does anyone has any ideas?

Thanks,
Hongquan
