This is exactly what I need! Yes, I agreed with you that to do so, the macro parameters should be relatively small (which in our situation, yes). Thank you all for the valuable suggestions! These are extremely helpful! Jerry

Hi, Rick: This might be a possible solution. However, what I truly need to do is: define a macro (similar to a function) to perform some calculations based on matrix and return a final answer. Doing so, I'd like to enter the matrix as part of the parameter when I call to run this macro, so that it can be read into IML. Hopefully it explains. Sincerely Jerry

Thank you so much for the quick response. Sorry that I did not explain my question clearly. What I intend to do is: I want to write a macro, for example: %macro testmacro(counts=);, where counts is a 3*2 matrix. Next, inside this macro, I will run proc iml to perform several tasks (based on some algorithm) via the elements of "counts" matrix. Now, can I run such macro as: %testmacro(count=(17 24, 36 49, 62, 98)), so that I can import this 3*2 matrix into proc iml? Sincerely Jerry

Hello, I'd like to ask for help. Here is my main body of PROC IML: proc iml; weights = {0 0.5, 0.5 0, 1 1}; counts = {145 34, 71 59, 76 38}; ... I am wondering how I can write a macro such that "counts" is entered as a macro variable when calls for the macro. And then, this variable will be read into proc iml just as what I showed above? I am new to this area, so my question sounds naive. Any suggestion is appreciated. Thanks Jerry
