IBM Scan Codes

                The following table is nothing to do with ASCII, but has been requested by a number of you out there. When a key on your keyboard is pressed, a code is sent which can be recognised by software. Programmers will find the most use for this table to map keys to actions for the function keys etc. 

















 

 

EBCDIC

ASCII is not the only format in use out there. IBM adopted EBCDIC (Extended Binary Coded Decimal Interchange Code) developed for punched cards in the early 1960s and still uses it on mainframes today. It is probably the next most well known character set due to the proliferation of IBM mainframes. It comes in at least six slightly differing forms, so again here is the most common.

It cuts right to the essential information, providing the perfect balance between too many details and too little information. I bought another well-known Java book, but I spent several hours trying to learn what I learned from your book in about 45 minutes." That's what one developer wrote us about the JDK 5 edition of our core Java book. Now, you can expect that same practical, time-saving approach in the current edition that covers the latest version of Java, Java SE 6. What you'll learn from the SE 6 edit...
