Easy.  Do something like this.....

$eval `awk -f awks`

where awks is:
{
	print $1 "=" $2;
}
or something like that.  With input of
abc def
xyzzy plugh
^D
you will find that $abc is def and $xyzzy is plugh, when you
are back at the shell.

This format requires that you are using ksh or sh.  For csh, the line
that formats the setting arguments should be
print "set " $1 " " $2;

Hope this helped.
