What I want to do is this: I want to have the same project in two environments. In one environment I would only have names that functioned as calls for the model to compile and in the other environment I would have the code written

Thanks!!

You may use one as code base,  
and use Reexport.jl to export and expand the methods in another.

Hello @vavrines , thanks for the suggestion  
This is the model I want to leave one as a code base

```julia
using JuMP, GLPK, GLPKMathProgInterface
ModelD = Model(GLPK.Optimizer)

t = 1:4
w = 1:2
l = 1:4

T = t
W = w
L = l
@variable(ModelD,eh[L,T,W]>=0)

for w = 1:2, l = 1:4, t = 1:4
    if 4 < 18
        h3 = @constraint(ModelD,eh[l,t,w] <= eh[l,t,w])
        println(h3)
    end
end

```

I’m trying to do exactly what you said, but I still haven’t been able to use the command. I read some things on the internet but I didn’t find any example that would help me with what I need. Can you help me?
