etc.ASCII Values and Characters: Each ASCII character is associated with an integer value. For example, the ASCII value of the uppercase letter 'A' is 65, while the ASCII value of the lowercase letter 'a' is 97. The ASCII value of the digit '0' is 48, and the ASCII value of a s...
Programmers use the design of the ASCII character set to simplify certain tasks. For example, using ASCII character codes, changing a single bit easily converts text from uppercase to lowercase. The capital letter "A" is represented by the binary value: 0100 0001 The lowercase letter "a" is...
For example, Bell is value 7, Control plus G, often shown in documents as ^G. Notice that 7 is 64 less than the value of G (71); the Control key subtracts 64 from the value of the keys that it modifies. For the text version of the following tables, click Control Characters and...
