In julia-1.0 I called a function"readdata()" that I defined in a file called “readdata”, from a start-up code in another file “main”.  
In julia-1.6 that does not seem to work anymore. I get “UndefVarError: readdata not defined”  
What is the problem and how can I solve it?

For the call `readdata()` to work, you must have first run either `readdata() = something` or

```julia
function readdata()
    something
end

```

. If you have that in a file, running `include("thatfilename.jl")` would do the trick.

I have put “include(“readdata”)” in my start-up file “main”.  
When I try to run “main”, I get SystenError: “No such file or directory"

Did you put `include("readdata")` exactly? Are you sure it shouldn’t be something like `include("/home/jaap/readdata.jl")`?

At first I’ve put readdata.jl but that didn’t work. After I changed it to readdata (without.jl) my function readdata() was apparently actually called, but I got “Paused on exception” and a lot of text about CSV.

So I guess that’s the next problem.

Not sure what to do about that.
