字库终极减肥的思路：
使用压缩字库－－XZL就是这样！
如果能有人编写挂接程序，就成功了！！！
而且所有汉字系统都行－－只是基本内存占用太多！

附件中是昆明明星公司的YSZK.EXE。

谁知道INT6Ah的调用接口？请提供一下！

YSZK.EXE基本内存占用多少？

INT6Ah的调用接口可試著查詢一下x86/MS-DOS Interrupt List。

Re qwe1234567:
TSR约占内存68Kb。

Re Wengier:
我说Int 6Ah指的是YSZK驻留后所占的中断。它是昆明明星公司的产品，应该与ACIOS中国龙类似吧！谁有中国龙的字库中断调用入口、出口参数，请帮个忙！

那比TW占内存的大！

那当然啦！
压缩字库是少占外存(磁盘)、多占内存，XZL就是！
所以只适合启动软盘！

YSZK是不是比XZL更加小？

这个问题看你怎么理解。YSZK只是字库载入模块，汉字系统至少要包括字库载入、显示、键盘三大模块，还没有加上打印及其它功能。每一模块都要消耗内存(基本、扩展、扩充等)，否则你就得做成硬卡。

第1楼的YSZK.EXE直接调用的话会死机！请改动4个字节就可以运行了。
步骤如下：
1）REN YSZK.EXE YSZK.EX
2）DEBUG YSZK.EX
　E 200 EB 29
　E1065 EB 29
　W
　Q
3）REN YSZK.EX YSZK.EXE
这样就能正常调用了。

:-( 但是，我还是取不出字模信息。调用规范估计是：
入口：AX=汉字内码
出口：DS:SI指向字模信息存储的缓冲区首址
不知道哪位汉字系统高高手能帮帮忙！！！！！！！！！！！！！！！！！！！！！！！！！

如果成功，我就可以把启动盘上用的汉字系统体积大大缩小，只有70K到100K了！！！

谢谢yaya提供的资料！

不过，我这儿说的INT 6Ah是指以YSZK.EXE自己替换掉的字库载入中断，ACIOS 3.x版不知道谁有？因为它们都是昆明明星公司的产品。

我的启动盘用的是天汇汉字系统，但有时也想用用别的汉字系统，可网上找来的天汇汉字系统都不带退出程序，我要怎么退出啊。

先按Ctrl F5，再选按0，就能退出了。

倒哦,贴了好多表情,呵呵
对了,这里的矢量压缩能不能大概介绍一下?
我还是对矢量字体等矢量图形对象感兴趣一些.
