Object Progamming Training Course
Object Programming and the Object Graphics Library is a three-day course for advanced IDL programmers. Its purpose is to introduce the principles of object oriented programming in IDL, and to demonstrate those principles by writing programs that use the object oriented graphics library in IDL.
Each course is tailored specifically to the interests and abilities of the course participants. Participants should come prepared with a particular object-oriented programming task in mind. The vast majority of time in this class will be spent working on a programming project under the supervision of the instructor.
