How to draw a filled band defined by two curves

Dear Sir/Madam,

one question, I use two curves to define a allowed region and want to fill the allowed
region with certain color. Is it possible to do it in ROOT? Could you show me a simple example? Thank you very much for your kind help.

Best regards,

see example in the attached macro.
