control code. The term macro is from the jargonese
Here is how Delta’s macro works. You define your macro by telling Delta what normal control codes are to be included in the macro. Then you can use the macro any time that you want and Delta will do all the things that you included in the macro defini- tion. You can include up to 16 codes in a single macro. You can even use the macro to store a frequently used word or phrase. There are two control codes for the macro: one to define it, and one to use it. They are given in the table below.

To see how this works we can build a macro that will reset the printing style to normal, no matter what style it may be to start with. The following program will define a macro to do this.
