| − | '''Case sensitivity''' occurs when data, particularly [[string]]s, which differ only in letter case, are considered different. An algorithm or function that exhibits case sensitivity is said to be '''case-sensitive'''; one that does not is said to be '''case-insensitive'''. For example, the Pascal compiler is case-insensitive, because every reserved word and every identifier may be typed in uppercase, lowercase, or mixed-case, with no difference whatsoever to the meaning.
