using flyspell-region from another function

[henri-biard]

Have written a function that calls "flyspell-region".



Naturally this needs the BEG and END of the region to be passed.  How should I 
call flyspell-region, meaning, what should I pass to it ?



(defun myspell ()

    (interactive)

    (flyspell-region beg end))



Want to select the region then call  "M-x myspell".



Do you know how I can use the superior aspell ?
