javascript to a seperate folder?

Hiya all, Sorry about this, I feel a bit thick asking this but I really need to know.
I know that javascript in the head of the document should be kept in a seperate file so that the robots don't have to trawl through it, but what is the best way to do this?
Is it simply a case of highlighting it all then cut and paste it into a folder marked .js?
Im sure it cant be that simple but then Im also sure it can't be that hard.
Anyone shed any light on the subject? Please.

you have the javascript as follows:

<SCRIPT LANGUAGE="JavaScript">

<!--
xyz
// -->

</SCRIPT>

then to call it up, you would need to copy:

<!--
xyz
// -->

into a text file and save it as java.js (or whatever)

then open up the java.js file and delete the commment
tags (<!-- // -->) as these will just **** things up.

now go back to your original page and you should have:

<SCRIPT LANGUAGE="JavaScript">
</SCRIPT>

change it to the following to call up the javascript:

<SCRIPT LANGUAGE="JavaScript" src="java.js"></SCRIPT>

(ie. just add src="" to it, just like an image calls
up it's source <img src="x.jpg">)

hope that helps

Cheers fraggle. Thats great, I new it wouldn't be too difficult but I wasn't sure how to make things call up the javascript.
Thanks again.

oops ... i copied that from an email i sent to a friend a couple of days ago and looks like i left a dodgy word in there

No porblem anyway

Thats fine, Might as well say it as think it I say.

Tried it out and all works perfectly. Cheers for the tip.
