http://www.iges.org/grads/gadoc/script.html is a good place to get started, namely, the section on functions.

Furthermore, if you surround your entire script code in a function (call it whatever you want, but MAIN is a common name), any args within the function call can get passed into the script code from the command line instead of having to set them in the code or ask the user to input them after invoking the script.  It makes for a nice easy way to call a grads script from some other scripting language like C-shell with the flexibility of using whatever arguments you want.
