Subject:      IML - Defining matrices - is there a better way?

Hello,

I am using PROC IML to program a simulation.  I would like to define a
matrix, and I know this matrix will have four columns, but I do not know
how many rows this matrix will have until run time, nor do I know what
values are actually in this matrix until the program is run and sets
them.  How do I define such a matrix?

If I knew that I wanted 8 rows, then I was thinking of doing something
like this:

srs={ [4] ., [4].,[4].,[4].,[4].,[4].,[4].,[4]. };

but since I don't always know that there will be 8 rows, I'm not sure
what I should do.  Any help would be greatly appreciated.

Thank you,

Kim
