List of Computer Character Codes
1) 97 is the code for lower case “a”
2) 65 is the code for upper-case “A”.
3) 32 is the ASCII code for blank space.
The following is from website: http://www.cs.tut.fi/~jkorpela/chars.html
A mapping, often presented in tabular form, which defines a one-to-one correspondence between characters in a character repertoire and a set of nonnegative integers. That is, it assigns a unique numerical code, a code position, to each character in the repertoire. In addition to being often presented as one or more tables, the code as a whole can be regarded as a single table and the code positions as indexes. As synonyms for "code position", the following terms are also in use: code number, code value, code element, code point, code set value - and just code. Note: The set of nonnegative integers corresponding to characters need not consist of consecutive numbers; in fact, most character codes have "holes", such as code positions reserved for control functions or for eventual future use to be defined later.
Introduction to Character Codes
Character Codes: the Basis for Processing Textual Data
What makes personal computers useful to the majority of people is not that they can process numerical data--yes, a lot of people still prepare their tax statements with a handheld calculator, not a personal computer!--but that they can process textual data. Almost anyone would agree that the overwhelming majority of personal computer users employ word processors more frequently than other type of application.
