Dear Friends, In my running PTB program, i ask subjects to press numbers such as "1" and "2" or characters such as "a", and "b" for responses, but when I exit the program,I found the numbers and characters were just displayed in my Matlab script, this cause some accidental error when i run the program for next subject. Do you know how to prevent the display of response into the script. Thanks in Advance! John ---

Either run the program from the command window or use ListenChar.
