SG-IO/l5 is a multi-lingual printer for it can speak in eight

languages! SG- lo/ 15 changes languages by changing 11 char-

acters that are different for the different languages. These sets

of characters are called international character sets. The control

codes to select the international character sets are given in Table

8-5.

The characters that change are shown beneath their ASCII code

in Table 8-6.

n The macro control code

The last of our group of miscellaneous control codes is definitely

not the least. It is a user-defined control code, called a macro

control code. The term macro is from the jargonese

macro-instruction which refers to an instruction that “calls,” or

uses a group of normal instructions. In computer programming

macro-instructions (which are similar to subroutines) save pro-

grammers a lot of time and effort. SG-10/15’s macro can save

you a lot of time and effort also.

Here is how SG-10/15’s macro works. You define your macro

by telling SG- 10/l 5 what normal control codes are to be included

in the macro. Then you can use the macro any time that you

want and SG-lo/15 will do all the things that you included in

the macro definition. 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 8-7.

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.
