this is my program
list={'AOA','CAS','IAS','ALT'};
prompt='Enter variable name';
a=input(prompt,'s');
b=strcmp(a,list);
if input does not matches with the list of variables then it must show an error 'Variable not found, please try again' (for three times) & if the user enters invalid variable for three times the program should be terminated.
