Where did you read about that function? That source is very outdated: `readall(io)` was replaced by `readstring(io)` in Julia 0.5, and then `readstring(io)` was replaced by `read(io, String)` in Julia 0.7.

If you are using Julia 1.X you should use `read(io, String)`.

Thank you, that explains why it has been driving me nuts. (I am on day 2 of testing Julia, so I naturally assume that if something is not working, it must be me doing something worng)

It was here: [readall(filename::AbstractString) » Julia Functions](http://www.jlhub.com/julia/manual/en/function/readall), hit by Google.  
Only after you mentioned it, did I notice that I’d hit a page that is not official documentation.

I will delete this post after a while so as to avoding further infesting google with hits to this deprecated function, and I will also try to add a comment on the page at [jhub.com](http://jhub.com)
