One of many nice merits of Unix is the immense array of unfastened and cheap software program instruments which are to be had for the platform. Programming with GNU software program offers an summary of ways C and C++ programmers can use a few of these instruments: the source-code editor Emacs, the gcc compiler, gdb debugger, gprof profiler, and the RCS version-control process. The ebook deals a quick-paced instructional that, in contrast to a few introductions to Unix instruments, is very inquisitive about the desires of C programmers.

Using tell Statements When you want to target a program with your commands, you have to let AppleScript know which program to talk to. For such purposes, the tell statement is your best friend. Say you want the Finder to open your Home folder, so you can copy some files onto your desktop. To do this, enter these commands in Script Editor, then click Run: tell application "Finder" activate open home end tell Everything after the tell command is directed at the program you specifyin this case, the Finder.
Figure 1-10. If you've never seen an AppleScript before, you may be surprised at how simple the code looks. As you can probably guess from the commands in the window, this script simply opens the Applications folder in the Finder. 34 Part I: AppleScript Overview Part I: AppleScript Overview 35 At this point, you can click the Run button to see what the script actually does (in this case, the script opens a new Finder window and takes you to the Applications folder). 2. Analyzing How It Works The next step in working with a script, of course, is understanding how the script actually works.
You can run, rename, and organize these scripts, as described on the preceding pages. But if you're just starting to learn AppleScript, these scripts can be lifesavers. Not only can you examine how the scripts work, but you can also make changes and see how they affect the scripts' behavior. Best of all, if you get stuck when writing a new AppleScript, you can copy some of the code from the Script Menu's scripts and paste that code right into your own script. 1. Opening a Script The first step in working with a script, of course, is opening it up.
