Error in Goddard example

[horasio]

Julia 1.10.2. Up-to-date modules, as of 2024-03-29. I've copied the example code into a single file, and I include() it. It did work a few weeks ago. But does not work anymore; see error message below. I'm very new to Julia, so it may be a bug from my Julia installation due to a mistake from me, but I don't know how to check that.

To start, you should set the name of the optimal control problem and the name of the solution.
For example, you can type:

    ct> NAME=(ocp, sol)

Thanks for the message. I have the same problem. Actually, there are many changes from the new release of Julia and we need to clean our package.

[ocots]

This should be ok also now! Thanks again @horasio!

[ocots]

Need to:

]
pkg> update

@horasio note that the REPL feature is rather experimental (though nice)
