            var form = $('form[name=sample]').clone();
            $(form).removeAttr('name');

            var editor = CodeMirror.fromTextArea(this, 
            {
                lineNumbers: true,
                matchBrackets: true,
                mode: "application/x-httpd-perl",
                tabMode: "shift"
             });
                editors.push(editor);
        });

</script>

2)

<script type="text/javascript">

    function execute() {
            p5pkg.CORE.print = function(List__) {
                var i;
                for (i = 0; i < List__.length; i++) {
                  document.getElementById('print-result').value += p5str(List__[i])
                }
                return true;
            };
            p5pkg["main"]["v_^O"] = "browser";
            p5pkg["main"]["Hash_INC"]["Perlito5/strict.pm"] = "Perlito5/strict.pm";
            p5pkg["main"]["Hash_INC"]["Perlito5/warnings.pm"] = "Perlito5/warnings.pm";
            var source = editor.getValue();
            alert(source);
            var pos = 0;
            var ast;
            var match;
            document.getElementById('print-result').value = "";
            try {
                var start = new Date().getTime();
                var js_source = p5pkg["Perlito5"].compile_p5_to_js([source]);
                var end = new Date().getTime();
                var time = end - start;
                // run
                start = new Date().getTime();
                eval(js_source);
                end = new Date().getTime();
                time = end - start;
            }
            catch(err) {
                //document.getElementById('log-result').value += "Error:\n";
                  }
        }
    </script>

Now my problem is i want to access the editor defined in first javascript as 

var editors = [];
        $('textarea[name=codeguru]').each(function() 
        {
            var editor = CodeMirror.fromTextArea(this, 
            {
                lineNumbers: true,
                matchBrackets: true,
                mode: "application/x-httpd-perl",
                tabMode: "shift"

the only way I can think is to pass the variable into the other functions as a variable

function otherJavaFile.myFunction (myVariable);

or alter a variable in the HTML i.e. the custom data-value and then the other script can access it. I don't like global variables.

// Sheet 1
$("#myDiv").attr("data-variable",yourValue);

// Sheet 2
 var secondVariable = $("#myDiv").attr("data-variable");

buddy i am not comfortable with jquery...
I hope you are looking forward for the iframes/frames on same document[window sharing]. Based on my knowledge of Javascript DOM to access a variable defined in one document inside another document.You have to use document.importNode(original Node as in other document,boolean) method as per DOM 2.
Do something like this for javacript code ...
documentI(original variable/node present here)- iframe.contentDocument.getElementsByTagName(/Tag name of Node/)...
documentII(node to be cloned here)- document.importNode(originalNode,True)

I hope this works

If you leave out var while defining variables they will be globally accessible.

So

pre = this;

instead of 

var pre = this;

would make pre accessible from every function.
