Concatenating Different # of Variables

Hi, I'm quite new at unix and was wondering if anyone could help me with this.

I have 2 arrays:
eg. STAT[0]=online, STAT[1]=offline, STAT[2]=online
WWN[0]=xxxx1, WWN[1]=xxxx2, WWN[2]=xxxx3
I got these information from a script using fcinfo hba-port that runs through a loop.

Now, I want to store (concatenate) them into one variable, say OUTPUT, which will have some kind of format like
HBA at xxxx1 is online ;; HBA at xxxx2 is offline ;; HBA at xxxx3 is online ;;

The thing is, depending on the server, the number of HBA card varies. How should I go about doing it?

The section of the script that stores the values into the array is:

HBA_COUNT=`sudo fcinfo hba-port | grep -i state | awk 'END{print NR}'`
while [[ $INDEX1 -le $HBA_COUNT ]] ; do
HBA_STAT[$INDEX1]=`sudo fcinfo hba-port | grep -i 'state' | awk 'NR=='$INDEX1 | awk '{print $NF}'`
HBA_WWN[$INDEX1]=`sudo fcinfo hba-port | grep -i 'Port WWN' | awk 'NR=='$INDEX1 | awk '{print $NF}'`
(( INDEX1=$INDEX1+1 ))

Thanks in advance

NVM... I just figured it out... I just did OUTPUT=$OUTPUT"HBA @ "${HBA_WWN[$INDEX1]}": "${HBA_STAT[$INDEX1]}" ;; " with OUTPUT="" defined outside the while loop.

for(( i = 0; i< ${#HBA_WWN[@]}; i++))
  Output=$Output"HBA at ${HBA_WWN[$i]} is ${HBA_STA[$i]} ;;"
echo $Output
