wrapping a function in a function and passing arguments.

I have a section of code that works but I need it to be run multiple times, seems like a perfect time for a function. But, I can't seem to wrap it in another function and pass arguments to the saveWeb3 function. I'd like to pass arguments for bookName, bookNameSuffix(_WEB), bookCode, bookcode suffix(_Web.jpg). Any advice?

thanks for your time and help.

bt.target = "photoshop";

function saveWeb3(){
var saveFileTif = new File("~/Desktop/"+bookName+"_WEB/"+bookCode+"_WEB.jpg");

var pdfOpenOpts = new PDFOpenOptions;
pdfOpenOpts.antiAlias = true;
pdfOpenOpts.bitsPerChannel = BitsPerChannelType.EIGHT;
pdfOpenOpts.cropPage = CropToType.TRIMBOX;
pdfOpenOpts.mode = OpenDocumentMode.RGB;
pdfOpenOpts.resolution = 72;
pdfOpenOpts.suppressWarnings = true;
pdfOpenOpts.usePageNumber  = true;

var theFile = (File("~/desktop/TempFile_01.pdf"));
app.open(theFile, pdfOpenOpts);

var currentWidth = app.activeDocument.width;
var currentHeight = null;
var currentResolution = 72 ;
app.activeDocument.changeMode(ChangeMode.RGB);

if(app.activeDocument.width.value>app.activeDocument.height.value){//Landscape
  app.activeDocument.resizeImage(
                 //currentHeight,
                  new UnitValue(800, "px"),
                  currentHeight,
                  currentResolution,
                  ResampleMethod.BILINEAR);
	}else
  {//Portrait
    app.activeDocument.resizeImage(
                   //currentHeight,
                    new UnitValue(600, "px"),
                    currentHeight,
                    currentResolution,
                    ResampleMethod.BILINEAR);
                  }

function SaveJPEG(saveFileTif, jpegQuality){
jpgSaveOptions = new JPEGSaveOptions();
jpgSaveOptions.embedColorProfile = true;
jpgSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
jpgSaveOptions.matte = MatteType.NONE;
jpgSaveOptions.quality = jpegQuality;
activeDocument.saveAs(saveFileTif, jpgSaveOptions, true,Extension.LOWERCASE);
}
SaveJPEG(saveFileTif, 8);

//Close open Pshop doc
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}

//convert the function into a string
psScript = "saveWeb =" + saveWeb3.toString() + "\rsaveWeb();";
//After converting the function into a string you need to replace
//the word bookCode in that string with the actual content of that variable.
//replace the word bookCode in the string with the actual content of the variable
psScript = psScript.replace(/bookName/g, "\"" + bookName + "\"").replace(/bookCode/g, "\"" + bookCode + "\"");

bt.body = psScript;

bt.onResult = function(resObj)
    {
        var myResult = resObj.body;
    }

bt.send(100);
