I guess you mean something like this:

fileID = fopen('data.txt');

C = textscan(fileID, '%s %s','delimiter', ' ');

fclose(fileID);

column1 = C{1}, column2 = C{2}

Thanks for the help, just another qn. If i were to read the data in each columm separately, is there any way i can verify whether each row in the 1st column is a 16 ASCII character and the second column is either 'encrypt' or 'sign'?

i.e : After extracting the data form the file,

i want to verify rowwise 'DEADBEEFDEADBEEF' is a ASCII character then correspondingly verify ' encrypt' and not 'sign'

this process will loop until theres no more data, meaning we have no idea how much data we are given in the text file. Yup greatly appreciated if u give me some advice.
