High-level language (taking basic grammar as an example): print CHR$(27)+ control string;
Command line (via etc TL): etc TL/parameter1/parameter2. ...
~ symbol (the text editor is used to control the printer): ~ p88t24w2z2;
Because of this control code, Eternal Chinese is always incompatible with ANSI. SYS, even in conflict with it, even some English software will be affected if it controls the cursor or screen through ANSI.SYS. Eternal Chinese system resides in the system in TSR mode, taking over the screen interruption of DOS system in the original English environment, INT 10H, drawing Chinese characters with 16 or 24 font files, and storing Chinese characters internally in double-bit (16Bit) mode. Because of the need for high-resolution display ability to draw Chinese characters, some early graphics cards, such as CGA, are not suitable for eternal Chinese. On the monochrome system, Hercules (Hercules graphics card), which was popular at that time, can be said to be the first choice to match the China system. The system also intercepts the INT09H and 16H processing input methods of the keyboard. When printing the form, use INT 17H for processing. So that the original operating system that handles English numbers can handle Chinese fonts. The high-order control code of Eternal Chinese adopts a syntax similar to that of ANSI screen control code, which is formed by adding control strings to ESC characters (0x 1B). The syntax of the following three output control strings was quite common at that time, and their functions were equivalent: high-level language (taking basic syntax as an example): PRINTCHR$(27)+ control string;
Command line (via etc TL): etc TL/parameter1/parameter2. ...
~ symbol (the text editor is used to control the printer): ~ p88t24w2z2;
Because of this control code, Eternal Chinese is always incompatible with ANSI. SYS, even in conflict with it, even some software will be affected if it controls the cursor or screen through ANSI.SYS. As for some large software, it will take over memory management or drawing memory, and there are considerable compatibility problems. For example, at that time, Windows3. 1 could not be accessed under the condition of eternal loading. You need to publish the Chinese system according to the following instructions:
ETCTL/C: IQ
For convenience, many users write this command as a batch file.
In addition, the hotkey Ctrl+ESC can switch between Chinese and English display modes, and the Chinese display mode can be restored by pressing the hotkey button again.
