a) [IBM] A unique bit pattern defined in a code. Depending on the code, a code point can be 7-bits, 8-bits, 16-bits, or other. Code points are assigned graphic characters in a code page. b) Location in a coding scheme. There are several notations of this position. In ISO the position is defined by its row/column in the code table (e.g. 5/14). In the IBM environment the hexadecimal representation of the location is prefered (e.g. X'5E').
