THE CONTROL CODE MAP

Speaking in graphic terms, the first two columns in most character sets, such as the one shown on Page D-6, contain control codes. Below is an alphabetical list of abbreviations used in character sets in this appendix and in the CTRL CODE column of the data byte map.

Pages D-12 through D-15 show all possible emulation-dependent control code maps. You select the control code map using either "Character Options" in the configuration menu or emulation control commands.
