Problem in attaching array type in struct

New to Julia

Does anyone know why this stretch is giving error?

´´´
struct lis
it = zeros(Int8, 10)
beg::Int8
en::Int8
tot::Int8
end
´´´
Thanks!

First, please surround your code with triple backticks.

Second, you cannot have variable assignments within a struct. The error message you get tells you this:
ERROR: syntax: "it = zeros(Int8, 10)" inside type definition is reserved

If you need this data inside a struct, create a field it::Vector{Int8} and then initialize the struct with lis(zeros(Int8, 10), ...).

Probably useful: Default value of *some* fields in a mutable struct.

See also Parameters.jl which allows you to set default values for fields.

Hello! thanks for the tip. The way I want to manipulate the struct, using hectorogen values, is giving this error.

struct lis
   it::Vector{Int8}
   beg::Int8
   en::Int8
   tot::Int8
end

ERROR: invalid redefinition of constant lis
Stacktrace:
 [1] top-level scope at none:0

You probably defined it before. You can only redefine a struct after restarting Julia.
