I have series of files saved via JLD2. I want to load them, one by one and do some operations on them.  
Generally I want to do following:

```julia
filename = "somefilename.jld"
@load filename

```

When I do it I get:

```julia
julia> @load filename
ERROR: MethodError: no method matching jldopen(::Symbol)
Closest candidates are:
  jldopen(::AbstractString) at /home/szpieg/.julia/packages/JLD2/ssCUN/src/JLD2.jl:292
  jldopen(::AbstractString, ::Bool, ::Bool, ::Bool) at /home/szpieg/.julia/packages/JLD2/ssCUN/src/JLD2.jl:209
  jldopen(::AbstractString, ::Bool, ::Bool, ::Bool, ::T; fallback, compress, mmaparrays) where T<:Union{Type{IOStream}, Type{JLD2.MmapIO}} at /home/szpieg/.julia/packages/JLD2/ssCUN/src/JLD2.jl:209

```

From the [README.md](https://github.com/JuliaIO/JLD2.jl), “when called with no variable arguments, `@load` requires that the file name is provided as a string literal, i.e., it is not possible to select the file at runtime.”

What @rafael.guerra said is correct.  
If you want to load a list of files then the best thing would be to use the `FileIO.load` API.

I must have skipped that part. It works great now, thanks.
