	Hi,

	I use 'rc' shell ported to Unix (Linux/AIX/HPUX).
	In most shells (including 'es' shell modeled after 'rc'),
	there is 'read' builtin command, to read a line from stdin and assign
	its words to one or more variables. But there is no such command in
	'rc'. How could I replace it ? 'head -n1' does not work as expected in
	most Unixes, as its reads are buffered and often eat more then one
	line from stdin. Should I write my own little hack in C ? :>

	Thank you in advance for your replies.
