28 nov 2018 9:50 pm est:using postgresql's psql command-style:
        '\q' to exit
        '\p' to play sound again,
        '\a' to show answer
        '\n' to go to next question without answering
        '\cq' to change quiz mode
        '\cl' to change language
        '\c' to show config
        '\d' to change digit amount
        '\dd' to change decimal digit amount
        '\s' to say a number

30 nov 2018 3:12 pm est:new command in above,is cancelled because command '\q' can
 become an answer for alpha-numeric-quiz,alphanumeric-nato-quiz,so 1st alphabet must
 be a blank-space because alpha-numeric-quiz,alphanumeric-nato-quiz never ask for a
 blank-space.but change from ' e' for exit to 'q' is for exit remain,because
 postgresql's psql use \q for exit.
30 nov 2018 4:45 pm est:fix bugs about printing listen-config.txt
            used to print in listen-config.txt:
            alpha_numeric_which_can_appear = 
            
             0123456789
             ABCDEFGHIJ
             KLMNOPQR
             ST
             UVWXYZ
             -~`!@#$%^&
             *()|\\<>/
             ?\
             ':;[]{},_
            
            now print
            alpha_numeric_which_can_appear = 
            {
             0123456789
             ABCDEFGHIJ
             KLMNOPQR
             ST
             UVWXYZ
             -~`!@#$%^&
             *()|\\<>/
             ?\
             ':;[]{},_
            }

            so local file listen-config.txt located in the same directory as listen.jar,
            must be deleted,so new listen.jar can recreate listen-config.txt in the same directory as listen.jar

30 nov 2018 8:24 pm est:listen.jar produce error if seeing listen-config.txt containing text being described in event '30 nov 2018 4:45 pm est'
30 nov 2018 8:30 pm est:forgot to upload new listen.jar, new listen.jar has been uploaded:https://drive.google.com/open?id=0B7-2cZC5HnE4ckpjaHV2QzYxalU
1 dec 2018 8:6 pm est:update listen-console-code/README.txt inside source-code https://drive.google.com/open?id=1dCPnQ4pRv6O59cY3V_YJ7bUIP_x8CBAN
