在屏幕上开出三个窗口:起止坐标为(5,10)和(15,30),(5,50)和(15,70),(18,15)和(22,65)。要求可用左右方向键选择左窗口或右窗口
在屏幕上开出三个窗口:起止坐标为(5,10)和(15,30),(5,50)和(15,70),(18,15)和(22,65)。要求可用左右方向键选择左窗口或右窗口为当前活动窗口。当一行字符显示满后(左右窗口一行显示20个字符,下窗口显示50个字符),窗口自动向上卷动一行,输入的字符仍显示与最低一行,窗口最高一行向上卷动后消失。用上下方向键可使活动窗口及下窗口内容同时上卷或下卷。输入‘ESC’后结束程序。(huangyujie)-screen out three windows : starting and ending coordinates (5,10) and (15, 30), (5,50) and (15.70) (18.15) and (22.65). Asked about the direction keys can be used to choose the left or right window to window to window current activities. When his characters show after the expiration of (his show window about 20 characters, the next window displays 50 characters), the window automatically scrolling upward here, the importation of characters showed that the minimum here, his highest window scrolling upward disappeared. Up and down direction keys enable activities under the window and window content, but on the next volume or volumes. Importation "ESC" end after the procedure. (Huangyujie)
