Calling this sequence generates the following output: Info:GlobalScope{scopedVariable} undefined Info:GlobalScope{scopedVariable} scopedVariable=globalscope type=string Info:TestScope{scopedVariable} scopedVariable=globalscope type=string Info:AlwaysLocalScope{scopedVariable} undefined Info:AlwaysLocalScope{scopedVariable} scopedVariable=AlwaysLocalScope type=string Info:TestScope{scopedVariable} scopedVariable=globalscope type=string In the generated output, scopedVariable is declared and assigned in GlobalScope The TestScope function verifies that scopedVariable exists Then, when calling AlwaysLocalScope, var declares that any reference to scopedVariable within the function is a local variable reference Thus, if there is a globally defined variable with the same name, it is not accessible within the scope of the function You have two ways to reference a global variable: referencing via the window property or creating a function that is external to the executing function (meaning it s not an inline function) and assigning the globally scoped variable..

BlackBerry does not have any logic that associates files to applications. Your app can write to any directory and read from any directory that it wants. When the app is deleted or upgraded, all existing files will remain in place.

Once you ve configured the service and have it running, you should be able to boot your client computers from it by pressing the N modifier key at boot, which instructs a client to attempt a network-based boot.

Mac OS X can boot from sources other than your default internal start-up disk through the use of modifier keys. When you power a system on, using these keystrokes will send commands to the system to perform the following:

This has a few ramifications. First, if you store actual program data in files, you will be responsible for maintaining your own versioning system. For example, you might tag the start of each file with the version number of the file format. This way, when future versions of the app try to read those files, they can quickly determine whether the files are compatible, and either translate or delete them if the file format has changed. Second, if you store media files like images or sounds, you can keep them in place and safely reuse on newer app versions. However, if you have a larger number of media files, they will still be taking up space after the user deletes your app; this may annoy some people. To be a good citizen on the phone, offer a choice within your app to clean up any such files. Users can run this option before deleting your app and return to a blank slate.

When a variable is not assigned, the typeof function returns undefined Once you assign a variable, typeof will return another value If a variable is defined in the context of a function, then each and every time the function is called, the variable before being assigned will be undefined At the global level, a variable can be unset by using the delete operator, as follows: delete scopedVariable; Usually, the delete operator is used to reset the property of an object When delete is used with an identifier, a global variable reference is deleted You cannot remove a reference to a function using delete Let s test another variation of scope using dynamic code In JavaScript, using the eval function will execute a JavaScript buffer, which tests when a variable will be considered global scope and when it will be considered local scope The AlwaysLocalScope function will thus be modified.

BlackBerry borrows the Record Management System from Java ME This provides a very convenient way to store sets of records, such as recent news headlines or restaurant details Records are stored as raw byte streams, without any version number or ordering Unlike files, RMS records are tied to a particular application If you delete an app, all its RMS records will automatically be removed When you install an upgraded version, the RMS records will remain in place and the new version will be able to read the old data If a user updates OTA through the web browser, she will be able to choose whether or not to retain the old RMS data Few applications actually want to deal with raw bytes, so typically an app will serialize and deserialize to translate between the RMS record data and some sort of object.
