Associative arrays are supported in some shells: ksh93, bash >=4.0, zsh
Code:
typeset -A array   # ksh and zsh
# declare -A array  # bash
index=""
str=""
while read value value2
do
        # new block ? - save previous block
        [ "$value2" != "" -a "$index" != "" ] && array[$index]="$str"  && str=""

        [ "$value2" != "" ] && index="$value" && str="$value2" && continue     # 1st line 
        str="$str,$value"
done < somefile
# save last block
[ "$str" != "" ] && array[$index]="$str"

#
#-number of values
echo "${#array[@]}"
#-keys
echo "${!array[@]}"

echo "bcdfmhs11: ${array[bcdfmhs11]}"

for key in ${!array[@]}
do
        echo "$key - ${array[$key]}"
done
