ISIM tcl命令行延伸到PC屏幕右侧太远

我的问题：
我创建了tcl文件以在ISIM中运行模拟，当我在整个运行时强制信号进行多级更改时，命令行变得太长（在屏幕右侧）。
有没有办法在ISIM继续执行的命令行上添加一行更改，就好像它执行1命令行一样？
例：
isim force add RAM_wr 0 -radix bin -time 0 -value 1 -radix bin -time 800ns -value 0 -radix bin -time 820ns -value 1 -radix bin -time 1300ns -value 0 -radix bin -time 1320ns -value 1
-radix bin -time 2050ns -value 0 -radix bin -time 2070ns
感谢帮助。



以下为原文

My question:
I create tcl file to run simulation in ISIM, the command lines is getting too long (to the right of the screen) when I force signal to many level changes during the whole run time. Is there a way to append a line changing on the command line that ISIM continues to execute as if it executes 1 command line?  
Example:
isim force add RAM_wr 0 -radix bin -time 0 -value 1 -radix bin -time 800ns -value 0 -radix bin -time 820ns -value 1 -radix bin -time 1300ns -value 0 -radix bin -time 1320ns -value 1 -radix bin -time 2050ns -value 0 -radix bin -time 2070ns

Thanks for help.
