Hi,

I found a big problem to declare an array with composite type.

In my code, I would like to write

tuple PM  
{  
npm::Int64  
nvm::String;  
}

indexes=PM  
push!(indexes,PM(1,“s”))  
push!(indexes,PM(2,“s”))  
push!(indexes,PM(1,“m”))  
push!(indexes,PM(2,“m”))

How could I write ths declaration ?

int countPVX[indexes]; ???

This is not even Julia code?

Neither is this.

Please try to put some effort into formulating your question. See [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757).
