+\ the forth command s" completly
+\ instead of s" foo" use "foo". The space
+\ after s" is no longer needed, instead it
+\ a part of the string. s" foo" and " foo"
+\ differ with the leading space in the latter

+\ strings live as long as the SOURCE is
+\ unchanged! Compilation is done to the
+\ flash if called in compile state.
