A coded character set (CCS) specifies how to represent a repertoire of characters using a number of non-negative integer codes called code points. For example, in a given repertoire, a character representing the capital letter \\\"A\\\" in the Latin alphabet might be assigned to the integer 65, the character for \\\"B\\\" to 66, and so on.

Morse code was introduced in the 1840s and is used to encode each letter of the Latin alphabet and each Arabic numeral as a series of long and short presses of a telegraph key. Representations of characters encoded using Morse code varied in length.
ASCII was introduced in 1963 and is a 7-bit encoding scheme used to encode letters, numerals, symbols, and device control codes as fixed-length codes using integers.
