RE: Repeat values in an array

Additionally, here's some sample code that should fit the bill:

a!localVariables(
  local!data: {15,0,0,23,0,0,0},
  local!nonZeroIndexes: a!forEach(
    items: local!data,
    expression: if(fv!item=0,null,fv!index)
  ),
  
  a!forEach(
    items: local!data,
    expression: if(
      fv!item<>0,
      fv!item,
      index(
        local!data,
        max(rdrop(local!nonZeroIndexes,count(local!nonZeroIndexes)-fv!index)),
        null
      )
    )
  )
)

Pretty much the exact same thing was answered several months ago, here. The only real difference in that case is the zero values are replaced by the next nonzero member instead of the previous, but that should require only a very simple adjustment of the code.
