3.2 Programming definitions
Many of the functions and data structures in the system can accept a limited number
of predefined values to determine their operation. The library defines several sets of
constant definitions for the valid numeric values, and the user should make use of
these when assigning values to system data and function parameters rather than
using their numeric equivalents.
