Answer

The macro facility presented thus far capable of inserting blocks of instruction in place of macro calls. All of the calls to any given macro will be replaced by identical blocks. This macro facility lacks flexibility: there is no way for a specific macro call to modify the coding that replaces it. An important extension of this facility consists of providing for arguments, or parameters, in macro calls. Corresponding macro dummy arguments will appear in macro definitions. . . . A 1, DATA 1 A 2, DATA 2 A 3, DATA 3 . . . A 1, DATA 2 A 2, DATA 2 A 3, DATA 2 . . . DATA 1 DC F '5' DATA 1 DC F '10' In this case the sequence are very similar but not identical. The first sequence performs an operation using DATA1 as operand; the second perform using DATA2. They can be considered to perform the same operation with a variable parameter or argument. Such a parameter is called a macro instruction argument, or dummy argument.
