喜欢在DOS下用QE.EXE来阅读文本文件,自已按键手痛。于是写了个自动向键盘缓冲区放UP
和DOWN键值的程序。
; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
; 文件名: AutoKey.asm
; 功 能: 自动向键盘缓冲区填充RIGHT 或 DOWN 键值 来移动光标
; Ctrl + Tab 停止填充
; Ctrl + → 填充RIGHT 键值
; Ctrl + ↓ 填充DOWN 键值
; Ctrl + ↑ 提高填充速度
; Ctrl + ← 降低填充速度
; 1. 第一次运行时常驻内存,再次运行则撤出内存
; 2. 适用于QE.EXE 和 TC.EXE, 不适于 EDIT.COM
; 3. 改进方向:
; A 在屏幕右上角显示当前速度
; B 填充RIGHT 键值时能自动换行
; 开发环境: IBM PC 486, MSDOS7.0(mswin95), MASM生成
