Mode Indication ¶

Meaning ¶

A mode indication is a bold word, an external object, that specifies a mode. Examples are int and complex. It is possible to introduce new mode indications via mode declarations. A mode indication is interchangeable with the mode it denotes within its range, which spans until the end of the current block. For example, the following mode declaration declares a mode indication tuple, which is visible until the end of the closed clause:

begin
  mode tuple = [2];
  ...
end

Mode indications are very often abbreviated and referred to as “MOIDs” or “moids”.
