Help how to make awk array
Hi expert,
I'm newbie in awk programming and now I have difficulty how to make awk array in ash shell. I have code below.
As you know ash shell doesn't support array and I cannot install bash
in my embedded environment.
So in order this code to work in ash shell then all array needs to be converted
Problem now while creating array in ash shell :

Code:
   scene[$SCNCNT]=$(echo $line | awk '{ print $2 }')

and calling array in ash shell :

Code:
   echo "MSG~heyu $(echo ${scene[${phone#*~}]})" | tee -a $LOG
   $HEYU $(echo ${scene[${phone#*~}]})

Can somebody help me on this?

Code:
#!/bin/sh

HEYU=/usr/bin/heyu	      # Path to Heyu
SED=/usr/bin/sed
SORTAZ=0                      # If 0, will sort by house code.

get_scenes() {
   SCENES=$($HEYU show usersyns | grep "usersyn")
   if [ "$SORTAZ" -eq "1" ]
    then 
       SCENES=$(echo "$SCENES" | sort)
   fi
   IFS=$(echo -en "\n\b")
   for line in $SCENES
    do
       let SCNCNT=$SCNCNT+1
       scene[$SCNCNT]=$(echo $line | awk '{ print $2 }')
       echo -n "S: " >> $LOG
       echo $line | awk '{ print "SCENE~" $2 "~'$SCNCNT'" }' | sed 's/_/ /g' | \
       sed 's/.*/\L&/; s/[a-z]*/\u&/g' | tee -a $LOG
   done
   IFS=$ORIGIFS
}

set_scene() {
   echo -n "S: " >> $LOG
   echo "MSG~heyu $(echo ${scene[${phone#*~}]})" | tee -a $LOG
   $HEYU $(echo ${scene[${phone#*~}]})
   sleep 1
   get_updates "$DEVICES"
} 

get_scenes
set_scene
