Code:
DATA=""
while read L
do
    if [ "${L:0:1}" = "#" ] 
    then
        echo -e "$DATA" # for check purpose
        [ -n $DATA ] && /statistic_program "$DATA"    # if there is data, process it (no data for the first occurence!)
        DATA=$L    # header, begin with a new set
    else
        DATA+="\n$L"    # \n:newline
    fi
done < input.txt
echo -e "$DATA" # for check purpose
/statistic_program "$DATA"    # process the last set
