Incidentally, to be more complete concerning defines: `defsubst' defines an inline function. The syntax is just like that of `defun'. `defconst' defines a symbol as a constant. The intent is that neither
programs nor users should ever change a value set by `defconst'. (You can change it; the value set is a variable; but please do not.) -------------------------------- I can understant the last sentence in parentheses .
What does it mean ? Thanks
