Hi, I just started using SAS today, I am using the University Edition1, I am trying to maximize a function. I type proc OPTMODEL; var x1: integer>=0; var x2: integer>=0; maximize z=8*x1+20*x2; con c1: x1+x2<=11; con c2: 3*x1+2*x2<=30; con c3: 1*x1+3*x2<=28; solve; print x1 x2 z; quit; but got the message: ERROR: Procedure OPTMODEL not found. bellow there is this message too: NOTE: The SAS System stopped processing this step because of errors. NOTE: PROCEDURE OPTMODEL used (Total process time): real time 0.04 seconds cpu time 0.03 seconds 66 67 OPTIONS NONOTES NOSTIMER NOSOURCE NOSYNTAXCHECK; what is wrong? is it a syntax error? I was just following advise from a tutorial and can not make this run.
