I couldn't find any primers online at Harris but you could have a look
at: http://www.harrisgeospatial.com/docs/idl_programming.html
Or, for reasonably priced books:
http://www.amazon.com/Practical-IDL-Programming-Liam-Gumley/ dp/1558607005
or
http://www.idlcoyote.com/coyotestore/index.php?main_page=pro duct_info&cPath=66&products_id=183
Please understand I'm not trying to be mean spirited here - I really
think you would benefit from some reading material about IDL programming.
cheers,
