A letter or symbol written below, and usually to the right, of another symbol for any of various purposes, such as to identify a particular element or elements of a set, to denote a constant value of a variable, or, in a chemical formula, to indicate the number of atoms of a particular kind in a molecule.
subscript(1) In word processing and scientific notation, a digit or symbol that appears below the line; for example, H2O, the symbol for water. Contrast with superscript.
(2) In programming, a method for referencing data in a table. For example, in pricetable, the statement to reference a specific price in the table might be pricetable (item), ITEM being the subscript variable. In a two-dimensional table that includes price and discount, the statement pricetable (item,discount) could reference a discounted price. The relative locations of the current ITEM and DISCOUNT are kept in two index registers.
(3) In programming, a method for referencing data in a character array. For example, in an array named keycode, keycode would refer to the first byte (starting with 0), the  being the subscript notation. The second byte would be referenced with keycode and so on. See pointer.
