Lingo program using FOR loop structures:

Model:

Sets:

hospital /wg wu wc ws/:weight;

input / nonphy exp beddays/;

output / patient nonpatient nurse interns/;

in(hospital, input): cost;

out(hospital, output): numbers;

endsets

min=E;

Data:

cost=285.2 123.8 106.72 162.3 128.7 64.21 275.5 348.5 104.1 210.4 154.1 104.04;

numbers=48.14 43.10 253 41 34.62 27.11 148 27 36.72 45.98 175 23 33.16 56.46 160 84;

enddata

end

请教一下如何写lingo里的for loop部分
