COMMENT:

	The RLaB comment symbol is `//' (same as C++). Any text the
	comes after `//' on a line is ignored.

	Additionally `#' can be used as a commet (same as shell).
	Again, any text after the `#' on a line is ignored. This is
	not the "official" comment symbol, but it works in order that
	`#!/usr/local/bin/rlab' may work on UNIX systems.

	Last, but not least, `%' will work as a comment symbol.
