how to use eval?

[Andy LW]

var fns = ['orde', 'no', 'kml', 'snf', 'td', 'ty', 'tn', ...up to 21
elms...];
var snv = new Array();

var vals = new Array();
for (i = 0; i < N; i++) {
for (j = 0; j < fns.length; j++)
vals[j] = some value;
snv[i] = new makeData(vals);
}

function makeData(vals) {
for (k = 0; k < vals.length; k++)
//the following line doesn't work
eval("this."+fns[k]+"="+vals[k]);
//neither this one
this.eval(fns[k]) = vals[k]);
}

how can i make it without writing it the long way:

this.orde = vals[0];
this.no = vals[1];
this.kml = vals[2];

and so on?

this[fns[k]] = vals[k];

But that seems like an odd thing to want to do.

You've got me wondering how he's managed to get OE to preserve the ' '
of '-- ' without OEQF.

But *good* software will only trim it from replies (*really* good
software would IMHO leave it present but greyed and copyable but not
editable, and would remove the greyed lines at the point of transmission
as news/mail).

To trim it from the version presented for reading would be ludicrous.

No Content-Type heade, no character declaration or
`Content-Type: ...; charset=us-ascii' will "allow"
this in OE.
