How you can call a function to load a data file, e.g.:

FName = 'MY_data'; % .txt data files that all contain the sequential name: MY_data1.txt, MY_data2.txt, etc.
N = input('Enter the number of data files to load:   ');
for ii = 1:N
    Name = stcat([FName, num2str(ii) '.txt']);
    data{ii} = read_data(Name);
end
function data=read_data(Name)
data=load(Name);
end
