Rhinoscript is based on VB script so a reference book of VB script is very helpful.  You need to understand how arrays are handled and the syntax for looping.  The Monkey Editor has a very useful help file that can be accessed by double clicking on any Rhino method. All of the methods have short examples that will give a sense of how to use the method.   Do you have a specific problem that you wish to solve with Rhinoscript?  I ask this because it would probably be easiest for me to write a script and explain what I've done relative to a problem that would be of interest to you rather than write for a randomly chosen problem that won't hold your attention.

im really a novice when it comes to the scripts , so its difficult for me to identify a problem but maybe some thing thats not just a surface development but uses data thats architecturally relevant site data like for eg sun pattern ect . 

thanks for ur reply btw

Attached is a script that will take as input the local latitude, year, month and date for a location and it will then output the local altitude at local noon as well as the declination of the sun on the day given and will also insert a point light into the Rhino scene to represent the sun.  The point light will be visible in Wireframe and Shaded Viewports.  Shadows will show when the scene is rendered with the Rhino Renderer but will not show up in the Rendered Viewport.  You can run the .rvb script file by dropping it on an open Rhino window.  Follow the Prompts on the command line but leave the Distance Prompt at it's default initially.   This value can be increased if the light is too close to the center of the scene.   To see how the script works you can open the .rvb file in the Monkey Editor.  It's well enough commented so that the flow should be fairly obvious even if you have questions about the syntax.  You can run it from the editor by hitting F5.  You can also run it from the Editor in Debug mode (Ctrl+F5) and go through it step by step and view the values being assigned to the variables.  Running a script in Debug mode is very helpful in finding errors and you need to get familiar with the Debug window if you're going to be writing your own scripts.  Let me know if you have any questions.

Here's a link to Pacal Golay's page of scripted utilities on the McNeel Wiki.

Here's another link to a simple script taken from a recent posting on the web news group that turns off the 'project to cplane' option (if it's on) before resetting the cplane origin.   It then resets the 'project to cplane' option if it had previously been on.

There are a number of people who regularly post on the news group who are very skilled scripters and are generally quite willing to assist with scripting questions.
