Question

lingo 变量赋值

model:
sets:
objk/1,2,3,4/:k;
obji/0,1,2,3,4,5,6,8,9/:i;
objj/0,1,2,3,4,5,6,8,9/:j;
endsets
data:
c(0,1)=14.9;c(0,2)=26.9;c(0,3)=30.1;c(0,4)=37;c(0,5)=12.2;c(0,6)=22.3;c(0,8)=21.2;c(0,9)=36;

c(8,6)=35.4;c(9,6)=47.4;
c(9,8)=53.9;
c(0,0)=0;c(1,1)=0;c(2,2)=0;c(3,3)=0;c(4,4)=0;c(5,5)=0;c(6,6)=0;c(8,8)=0;c(9,9);
enddata
min=@sum(obji(i):@sum(objj(j):@sum(objk(k):c(i,j)*x(i,j,k))));
@bin(x);@bin(y);
错误11，说是c的语句错误，求指教！
