how to use SAS debug your iml program?

shiyiming

Anyone know how to debug a SAS/ iml program? I have a "do while" and I want to see what is wrong within the loop.

Is there anyway that I can see the value of a variable while the programs is running?   

Thanks a lot!

data yourdataset / debug;
启动DEBUG窗口后，用'e 变量名'命令显示当前值。
具体使用方法请参考SAS HELP，里面写的很清楚详细。

I have a big problem right now. anyone can help me with that?
matrixa* matrixb*...*matrix(n-1)*inv(matrixn)=0
matrixa .... matrixn contain some variables. Now I want to solve the above equations to obtain these variable.  and I cannot work out the explict form of the above equation. any funtion for this question? I know there are some if AX=C THEN x=inv(A)*C. but now I don't know A.

Thank you very much!
