16.17. Action Statements

Given a column headed ACTION, the cells in successive lines result in an action statement:
  • Text in the first cell below ACTION is optional. If present, it is interpreted as an object reference.
  • Text in the second cell below ACTION is processed in two steps.
    1. The code snippet in this cell is modified by interpolating values from cells farther down in the column. For a singular insertion, mark the position for including the contents of a cell with the symbol $param. Multiple insertions are possible by using the symbols $1, $2, etc., and a comma-separated list of values in the cells below.
      A method call without interpolation can be achieved by a text without any marker symbols. In this case, use any non-blank entry in a row below to include the statement.
      The forall construct is available here, too.
    2. If the first cell is not empty, its text, followed by a period, the text in the second cell and a terminating semicolon are stringed together, resulting in a method call which is added as an action statement for the consequence.
      If the cell above is empty, the interpolated result is used as is.
  • Text in the third cell below ACTION is for documentation only. It should be used to indicate the column's purpose to a human reader.
  • From the fourth row on, non-blank entries provide data for interpolation as described above. A blank cell results in the omission of the action statement for this rule.

Note

Using $1 instead of $param will fail if the replacement text contains a comma.
