While true, and it does what the OP literally asked for, it isn't likely to be what he really needs.
My guess is that he is trying to manage 40 data arrays, which in Octave should probably be represented as a 2D array, where the i-th dataset is in the i-th row, y(i,1:end), and his _expression_ then is simply

x=y+a

If the datasets are of different length, a single array won't do and then he needs to use a cell array
where i-th dataset is in cell member y(i), and his _expression_ is

x=cellfun(@(x) x+a,y,"UniformOutput",false)
