        For example, in some cases I do not want to print non-ascii characters in hex dump, in others I do. ? How does a hex dump contain anything other than hex digits and space (to separate bytes). You might want a way of controlling whether to use upper or lower case letters (but I wouldn't bother).
In my case I follow format presented by some text editors I am used to. It includes both hex and actual data on the right. But I wouldn't insist that much on this particular one. Gennadiy
