I would recomend have separate external js files instead of an embedded <script> tag, but maybe this can help

If you want to call the file in an another js file then you have to refer that file in the calling file.
Ex.
Refer the files in the head section.
<head>
<script src="File2.js" type="text/javascript"></script>
<script src="File1.js" type="text/javascript"></script>
</head>
you can have your body tag something like this:
<body>
<script type="text/javascript">
Method2(); // Where you want to call method from another JS.
</script>
</body>
then, using first file
File1.js
function Method1(number) {
alert("Method1");
}
File2.js
function Method2() {
Method1("Method1 is called in Method2");
}
