Based on FIG. 8, a flow of displaying characters on the CRT 12 of the monitor device 1 will be described with reference to FIG. In step 80, the position information of the display character and one character of the character code stored in the data table 11b are read. In step 81, it is determined whether the character string is the last one or not depending on whether the position information N is "-1". Since the position information corresponding to the first character “TE” is “1”, the process proceeds to step 82. In step 82, it is determined whether the position information N of the current character and the position information N of the next character are both "1". Since the position information N of the next character is "2" here, the process proceeds to step 83. In step 83, the font data of the character "te" is read from the font ROM 15 and stored in the character processing VRAM 17 at the position of the first character. Next, in step 84, whether or not the display of one line is completed is confirmed by the position information N of the next character "".
Since the position information is “2”, return to step 80,
After reading the character code of the next character "" and the position information N "2", step 81, step 82, step 83
Proceed to, and set the font data for the character "" to the font ROM.
It is read out from the memory 15 and stored in the position of the second character of the character processing VRAM 17 based on the position information N “2”. Next, in step 84, the position information N of the next character "C" is "1".
Therefore, it is determined that the display of one line is completed and the process proceeds to step 84, and the data stored in the character processing VRAM 17 is changed to the display VRA designated by the display position data X1 and Y1.
Transfer to M18. After the transfer, the data in the character processing VRAM 17 is cleared and the process returns to step 80.

The characters "HA" and "" are also executed in the same manner as the processing of the characters "TE" and "" described above. However, in the data transfer to the display VRAM 18, the data is output from the previous output position in the Y direction so as to be located at the lower position by the font size until the display of a series of character data is completed.

The process for the next character "a" will be described. Since the position information read in step 80 is "1", the process proceeds to steps 81 and 82. In step 82, the positional information N of the next character "S" is confirmed, and since it is "1", it is judged as a single character. It is stored in a predetermined position of the VRAM 18. Then, the process returns to step 80.

The processing for the next character "su" will be described. Since the position information read in step 80 is "1", the process proceeds to steps 81 and 82. In step 82, the next position information N is confirmed, and since it is "-1", it is judged as a single character. Store.

Next, at step 80, the position information N is read. Since the next position information N is "-1", it is determined that the character string is the last one, and the process proceeds to step 87 to display the data in the display VRAM 18 on the CRT 12. The display result is shown in FIG. 14b.
