            i want to load a file but the problem is i don't want to use syntax load 'kl.txt' i want to use load filename where filename is assigned value of'kl.txt' I require this so that i can use load in functions so that i can pass filename aas argument .

        Try this robust approach:
baseFileName = 'kl.txt';
folder = pwd; % Or whatever folder you want.
fullFileName = fullfile(folder, baseFileName);
if exist(fullFileName, 'file')
  % File exists.  Read it into a structure.
  storedStructure = load(fullFileName);
  % Extract individual variables from the structure.
  a = storedStructure.a; % Or whatever the variable is called.
  b = storedStructure.b; % Or whatever the variable is called.
else
  % File does not exist.  Alert user
  warningMessage = sprintf('Error: mat file does not exist:\n%s', fullFileName);
  uiwait(warndlg(warningMessage));
  % Assign defaults in case we want to try to continue;
  a = 1;
  b = 2;
end
Actually, in my code I make it even more robust. I check if the structure has the field before trying to assign it. Let me know if you want that code.

      do you really want to use load with text files?
myfile = load([fileName,'.',fileExtension]); % load is for workspaces really
myfile = myfile.myfile;

				load() of text files is one of the fastest ways to read text data.

				filename = 'asset-v1_KPITedu+EDUTECIF1041+2019+type@asset+block@DATA123.xls';
data = readtable(filename);
load() is not defined for xls files.
