本程序可在长城0520CH微型计算机的屏幕上显示多种字体(宋体、仿宋体、黑体和楷书)和大小(16点阵、24点阵和32点阵、48点阵)的汉字及字符。程序由汇编语言写成,可常驻内存。程序调用灵活、方便,可以被BASIC程序所调用。16点阵(和32点阵)字模取自显示板上的硬字库,通过系统显示模块IN10H中的功能模块(AH=16H)来取字模点阵。24点阵(和48点阵)字模用的是CCDOS2.13所带的24点阵打印字库。通过读文件(INT21H中 This program can be displayed on the screen of the Great Wall 0520CH microcomputer a variety of fonts (Arial, imitation Arial, bold and regular script) and size (16 lattice, 24 lattice and 32 lattice, 48 dot matrix) of Chinese characters and characters. Program written in assembly language, can be resident in memory. Program calls flexible, convenient, can be called by the BASIC program. 16 dot matrix (and 32 dot matrix) fonts from the hard font on the display board, through the system display module IN10H function module (AH = 16H) to take the font lattice. 24 dot matrix (and 48 dot matrix) font used is CCDOS2.13 brought 24 dot matrix print font.
