PowerPoint provides two ways for you to edit headlines. The rst method is to click the View tab and, in the Presentation Views group, click Normal. In this view, click in the title area of the slide, and then start editing. The second method is to view the presentation in Outline format. In Normal view, the leftmost pane of the PowerPoint window contains an Overview area with two tabs: Outline and Slides. Click the Outline tab to see a list of headlines and, to the left of each headline, a number and a small icon of a slide. Click in the text of the headline you want to edit. As you make changes to a headline on the Outline tab, the corresponding text in the title area of the slide to the right is updated. You can drag the vertical line at the right side of the Outline pane to increase or decrease its size to accommodate the width of the headlines. The Outline tab can be useful for reviewing all of the headlines of the slides in a list that you can read from top to bottom. Later you can print this outline to use as speaker notes.

Note Only one code block can be passed at any one time. It s not possible to accept two or more code

blocks as parameters to a method. However, code blocks may accept none, one, or more parameters themselves.

If you do not use the BBP Storyboard Formatter, you will not be able to use the built-in custom layouts to format the Key Point, Explanation, and Detail slides, but you can still format them manually. To quickly do this, follow these steps:

It s also possible to store code blocks within variables, using the lambda method:

print_parameter_to_screen = lambda { |x| puts x } print_parameter_to_screen.call(100)

In Slide Sorter view, right-click the Call to Action slide, click Format Background on the shortcut menu, and in the Format Background dialog box, click Fill and then select Solid Fill.

As with accepting a code block into a method, you use the lambda object s call method to execute it, as well as to pass any parameters in.

Note The string method find does not return a Boolean value. If find returns 0, as it did here, it means

Note The term lambda is used due to its popularity elsewhere and in other programming languages. You

So far in this chapter, we ve covered the primary built-in data classes of numbers, strings, arrays, and hashes. These few types of objects can get you a long way and will be used in all your programs. You ll be looking at objects more in depth in 6, but before you get that far there are a few other important points you need to look at first.

A concept that s useful to represent within many computer programs is time, in the form of dates and times. Ruby provides a class called Time to handle these concepts. Internally, Time stores times as a number of microseconds since the Unix time epoch: January 1st, 1970 00:00:00 Greenwich Mean Time (GMT)/Coordinated Universal Time (UTC). This makes it easy to compare times using the standard comparison operators, such as < and >. Let s look at how to use the Time class:

You may also supply a starting point for your search and, optionally, also an ending point: >>> >>> 0 >>> 20 >>> 16 >>> -1 subject = '$$$ Get rich now!!! $$$' subject.find('$$$') subject.find('$$$', 1) # Only supplying the start subject.find('!!!') subject.find('!!!', 0, 16) # Supplying start and end
