system error?

[luching]

In setting up the VAR system, doesn't RATS 8.0 support the equations option anymore? For instance, the following seems to give an error:

system 1 to n
.....
end(system)

whereas the following seems to work;

system(model=varmodel)
.....
end(system)

How do I allow RATS to read 1,2,3...n as the equation numbers from "varmodel"? Any hint will be great.
