Subject:      passing in parameters to macro (newbie question)
Content-Type: text/plain; charset="us-ascii"

Can anyone help me trouble shoot the code below?

When I change %rand2(blnum=nk,fileName=test); to
%rand2(blnum=12,fileName=test);, then I get the output I desire (the B
dataset) .but when I keep it as is, it outputs the test dataset, which
is only the nk value and the B table is empty.  Do you know how I can
pass in the parameter nk and have the B dataset output like it would if
I passed in a number?

Thanks
Kim
