The A+ language implements the following changes to the APL language:
  • An A+ function may have up to nine formal parameters.
  • A+ code statements are separated by semicolons, so a single statement may be divided into two or more physical lines.
  • The explicit result of a function or operator is the result of the last statement executed.
  • A+ implements an object called a dependency, which is a global variable (the dependent variable) and an associated definition that is like a function with no arguments. Values can be explicitly set and referenced in exactly the same ways as for a global variable, but they can also be set through the associated definition.
