the data to be imported from A6 to D1000 . Can anyone please help me on this

Can you share a sample file, and what is your expected output? Also, note that naming variables dynamically is not a good idea: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval. You should not store the data in the variable name. Use an array to store the data or use some other data structures such as table() or struct().

You should try readtable function. if you need to customise use the function delimitedTextImportOptions and pass in the options into readtable function.

You can try the following.

if true
  fname = 'pathtofile.txt';
  opts = delimitedTextImportOptions('VariableNamesLine',3,'DataLines',6,'Delimiter','\t');
  out = readtable(fname,opts);
end

On R2020b, you can simply use readtable() on the file itself

T = readtable('data.txt')

'data.txt' is attached.

>> T.time
ans =
     1
     1
     1
     1
     1
     1
>> T.A
ans =
     1
     1
     1
     1
     1
     1
>> T.B
ans =
     0
     0
     0
     0
     0
     0
>> T.C
ans =
     1
     1
     1
     1
     1
