在ARX中有如下的句子：
int ff=10;
acedRetInt(ff);
执行以后，在命令行下输入 !ff ,返回nil,没有值是怎么回事啊？

在ARX中
1. using "defun" to create a command.(eg,test1)
2.
int test1(double a1,char a2[])
{
.....
as you say!
}
3. In lisp (or AutoCAD)
(setq ff (test1 3.122 "abcdeff"))
! ff
===================================
This means, you send datas (A double 3.122 and a string "abcdeff") from lisp to arx and get a returned data which saved in ff
