Illustrator export script

Question

Hi,
I was looking for a script that will allow me export to PDF with predefined PDF export preset.
I found this and I would like to instead of getting prompts which profile to choose (from the list), use that profile permanently (say it's number 7).
Also would be great if script would add to that exported file string of text at the end say like _exported1.pdf
Any ideas?
#target illustrator
if (app.documents.length>0){
var FolderRef = new Folder();
var folderResult=false;
try {
     FolderRef = FolderRef.selectDlg("Folder to save your PDF");
if (FolderRef!=null){folderResult=true;}
} catch (e) {
     alert("! Error on selecting folder:\n"+e+" !");
     folderResult=false;
var list=app.PDFPresetsList;
var Plist='';
for (var i in list){Plist+="\n"+i+" : "+list[i]}
var pIndex=prompt ('Choice your PDF preset by number'+Plist,10);
for (i=app.documents.length;i>0;i--){
     var PDF = new PDFSaveOptions();
     PDF.pDFPreset =list[pIndex];
     var saveName = new File (FolderRef+"/"+documents[0].name);
     documents[0].saveAs(saveName,PDF);
     documents[0].close();
alert ("Done!");

Where did the code come from then? Here perhaps? http://forums.adobe.com/message/2848958

W_J_T your code gives me this error:     Error 8: Syntax error. Line: 1 -> # target illustrator
Sorry, that is just the "space" between # target, it should be no space #target (I auto-formatted with my text editor and it added the space, I didn't catch it)
Does the version below do what you want? It should deal with what "rama@adobe" mentioned above, sorry I didn't look close enough at the code before when posting.

        // Get the file name minus the file extension, also remove spaces and replace with underscores
        var fileName = app.documents[0].name.substr(0, app.documents[0].name.lastIndexOf('.')).split(' ').join('_');
        // Combine the fileName with the fileNameAppend plus the .pdf file extension (the extension part however is probably is not needed and can be removed)
        var saveName = new File(FolderRef + "/" + fileName + fileNameAppend + ".pdf");
        documents[0].saveAs(saveName, PDF);
        documents[0].close();
    alert("Done!");
