    a!localVariables(
  local!X,
  {
  a!buttonArrayLayout(
    buttons: {
      a!buttonWidget(
        label: "Button",
        style: "OUTLINE",
        saveInto: a!forEach(
          items: enumerate(10)+1,
          expression: a!save(
            local!X[fv!index],fv!item
          )
        )
      )
    },
    align: "START",
    marginBelow: "NONE"
  )
})

    What do you want to save using a!save() ?  Can you provide us with more details

    For example, the above code doesn't need a forEach loop if you just want to update the items of an array. It can be simplified as

    a!save(
    local!X,
    enumerate(10)+1
  )

    But if you have a particular requirement which cannot be solved without a loop, then you have the code from Venky.

    A foreach would do that. But what do you want to achieve?

    Hello [mention:995c759ada07435883c8572879d4840b:e9ed411860ed4f2ba0265705b8793d05] 
    You will have to use a!forEach() and run your a!save()(Not recommended). Also do you have any particular variable that defines the number of iterations that has to be performed? 
    What will this a!save() perform exactly?
    If the Rule Input or Local variable that you are going to use for the target is same, You don't need to do the loop. May be a better explanation of your requirement would help all of us to give a better solution.

    This has been discussed on community quite a lot of times now - community.appian.com/.../function

    if(
  a!isNullOrEmpty(ri!inputArray),
  {},
  a!localVariables(
    local!data: a!forEach(
      items: ri!inputArray,
      expression: { value: fv!item }
    ),
    todatasubset(
      local!data,
      a!pagingInfo(
        startIndex: 1,
        batchSize: - 1,
        sort: a!sortInfo(
          field: "value",
          ascending: or(ri!ascending)
        )
      )
    ).data.value
  )
)
