Saving a copy of active AI CS 4 document as EPS Illustrator 8

Question

I have Illustrator CS4 (Windows version) and I need to save a copy of a currently open (active?) document (there could be multiple open documents but I don't need the script to cycle thru them, I just need it to work on the active document.) in Illustrator 8 eps format. The file needs to be saved in situ with the same name only extension should be .eps instead .ai.
How can this be done with JavaScript?
Action script records a specific path, so all files end up in the same directory as the file used for trecording the script step regardless of where the files are actually  located, so I hope that a JS can be used for this purpose.
The scripts I have found so far on the forum are much more sophisticated than what I need and seem to prompt user for the directory. I don't want the script to prompt user for anything.
Any help wit this will be greatly appreciated.
Thanks

Im not all that familiar with the PC stuff but this may work for you…
#target illustrator
function saveAsAI8()
     if (app.documents.length == 0) return;
     // Set a variable to the active document
     var docRef = app.activeDocument;
     // Check and strip off old extension
     var docName = docRef.name;
     var nameString = '';
     var extOffset = docName.lastIndexOf('.');
     if (extOffset == -1) {
          nameString = docName;
     } else {
          nameString = docName.substr(0, extOffset);
     // Get the name to the files parent
     var docPath = docRef.path.fsName;
     // Set up a save options object
     var epsOptions = new EPSSaveOptions();
     epsOptions.cmykPostscript = true;
     epsOptions.compatability = Compatibility.ILLUSTRATOR8;
     epsOptions.compatibleGradientPrinting = true;
     epsOptions.embedAllFonts = true;
     epsOptions.embedLinkedFiles = true;
     epsOptions.flattenOutput = OutputFlattening.PRESERVEAPPEARANCE;
     epsOptions.includeDocumentThumbnials = true;
     epsOptions.overprint = PDFOverprint.PRESERVEPDFOVERPRINT;
     epsOptions.postScript = EPSPostScriptLevelEnum.LEVEL2;
     epsOptions.preview = EPSPreview.COLORTIFF;
     // Make file object to new location
     var saveFile = new File(docPath+'/'+nameString+'.eps');
     // Use save as method passing new file path & options
     docRef.saveAs(saveFile, epsOptions);
saveAsAI8();
