Hello,
I'm trying to use PROC PLAN to assist with subject assignment for a study. Each of 60 subjects will wear 1 of 6 conditions while completing each of 2 tasks. I want to control for order effects with the tasks. I would like the first 30 subjects to be balanced across the 6 conditions and task orders (as much as possible) so that I can do an initial look at the data.
Is PROC PLAN appropriate, or is there another approach recommended?
I have SAS 9.4
Thank you in advance for your help.

proc plan might be too complicated (for me!), but what about:
data design;
do wear = 1 to 6;
do taskOrder = "1-2", "2-1";
do i = 1 to 5;
subject = rand("uniform");
output;
end;
end;
end;
drop i;
run;
proc rank data=design out=assign;
var subject;
run;
