MAK ING A LIVE presentation with Microsoft Of ce PowerPoint 2007 is complex and dif cult from a couple of perspectives. From a presenter s point of view, you have many things you want to say and show during a presentation, including your purpose, your key points, and the many thoughts, ideas, anecdotes, arguments, data, and evidence that back up your key points. You would like your audience to integrate the new information into clear understanding in long-term memory, as shown in Figure 3-1.

In 4 you used a special array called ARGV. ARGV is an array automatically created by the Ruby interpreter that contains the parameters passed to the Ruby program (whether on the command line or by other means). For example, say you created a script called argvtest.rb:

puts ARGV.join('-')

Learn how Beyond Bullet Points (BBP) addresses the limited capacity of your audience s working memory to process new information. See how you will use the BBP Story Template to create the foundation for your presentation that you will build upon with your narration and graphics. Prepare the BBP Story Template and review three ground rules for writing headlines.

of as well as those you re prepared for. It will also trap attempts by the user to terminate execution by Ctrl-C, attempts by functions you call to terminate by sys.exit, and so on. In most cases, it would be better to use except Exception, e and perhaps do some checking on the exception object, e.

You could run it like so:

The parameters are passed into the program and become present in the ARGV array, where they can be processed as you wish. Use of ARGV is ideal for command-line tools where filenames and options are passed in this way. Using ARGV also works if you call a script directly. On Unix operating systems, you could adjust argvtest.rb to be like this:

3

#!/usr/bin/env ruby puts ARGV.join('-')

And you could call it in this way:

In some cases, it can be useful to have a block of code that is executed unless something bad happens; as with conditionals and loops, you can add an else clause: try: print 'A simple task' except: print 'What Something went wrong ' else: print 'Ah...It went as planned.' If you run this, you get the following output: A simple task Ah...It went as planned. With this else clause, you can implement the loop hinted at in the section Catching Two Exceptions with One Block, earlier in this chapter: while 1: try: x = input('Enter the first number: ') y = input('Enter the second number: ') value = x/y print 'x/y is', value except: print 'Invalid input. Please try again.' else: break

But as you saw in 2, you also know what is happening from the audience s point of view in terms of memory. Sensory memory can see and hear a potentially unlimited amount of verbal and visual information, but only for a eeting second. Long-term memory can hold a potentially unlimited amount of information from 30 seconds to up to a lifetime. Yet the capacity of working memory to handle new information, the eye of the needle, is relatively limited for the few seconds it pays attention to what you are showing and saying. That means that effectively communicating a message is not as easy as creating a PowerPoint presentation and assuming that you can deliver it through an unobstructed pipeline to the passive minds of your audience. Instead, you have to set PowerPoint myths aside and engage the three research realities you learned about in 2 nding the right amount of new information to engage the limited capacity of working memory without overloading it, engaging both the visual and the verbal channels, and guiding the working memory of your audience to help them integrate new information into their long-term memory. Some of the Beyond Bullet Points (BBP) techniques you will use to accomplish this are new, some you already know, and some are old techniques used in new ways. If you re new to PowerPoint, you won t have to unlearn old habits; instead, you ll nd here a better way to use PowerPoint from the start.

You generally use command line arguments to pass options, settings, and data fragments that might change between executions of a program. For example, a common utility found on most operating systems is copy or cp, which is used to copy files. It s used like so:
