Redirection of the "read" command is not supported in the 4.3BSD Bourne shell;
it is supported in the System V Bourne shell. So, this works on SunOS and the
Pyramid's att universe, but does not on Ultrix or the Pyramid's ucb universe.

You can do what you want -- better I think -- using head(1):

	#!/bin/sh
	x=`head -1 $0`
	echo x = $x
