proc optmodel

I am new to using SAS for linear programming, but trying to teach my self some of the basics. I tried running the code below and the log said "Procedure OPTMODEL not found". This is just some simple code out of a SAS tutorial. Anyone know why it is having a problem with this? Thanks.

proc optmodel;

num a{1..3, 1..4}=[-5 3 1 8

5 5 4 6

4 6 0 5];

var x{1..4} >= 0;

max f = sum{i in 1..4}x;

con c{i in 1..3}: sum{j in 1..4}a[i,j]*x <= 1;

solve with lp / solver = ps presolver = none printfreq = 1;

print x;

print c.dual;

quit;

PROC OPTMODEL requires a SAS/OR license. You can run the following to see whether SAS/OR is installed:

proc product_status;

run;

Thanks. The log only says access, stat, IML, and graph. I am working off of a university license. Any ideas on how much more the sas OR cost?

I don't have any pricing information, and I suggest that you contact your SAS sales representative. If you don’t know who that is, you can use the contact info provided in this link:
