Tricky - Need help on Shell script variables

Shell Programming and Scripting

Hi, I have a requirement in which i have to read a csv file and put data in certain set of variables:
File content:

VP-DTL-REC-CNT, ,854840,0.00,VP-PAID-AMT, ,0,32280885.17,VP-PAT-PAID-AMT, ,0,9930244.32,VP-PAID-REV-CNT, ,484927,0.00,VP-REJ-CNT, ,369913,0.00, , ,0,0.00, , ,0,0.00, , ,0,0.00, , ,0,0.00,CYCL_SRCE_DT, ,01/25/2010 00:00:00,1

This is the code i have written:

var=`cat ${INFA_BALANCING_DETAILS}`
 for i in 0 1 2 3 4 5 6 7 8 9
  do
   for j in 1 2 3 4
   do
    v=`expr 4 \* $i + $j`
    u=`expr $i + 1`
    case "$j" in
      1 ) ACTN_0${u}_NM=`echo $var|cut -d"," -f"$v"` ; exit ;;
      2 ) ACTN_0${u}_CD=`echo $var|cut -d"," -f"$v"` ;;
      3 ) ACTN_0${u}_CNT=`echo $var|cut -d"," -f"$v"` ;;
      4 ) ACTN_0${u}_AMT=`echo $var|cut -d"," -f"$v"` ;;
      * ) exit ;;
    esac
   done
  echo "$ACTN_0${u}_NM" "$ACTN_0${u}_CD" "$ACTN_0${u}_CNT" "$ACTN_0${u}_AMT"
  done

My problem: The assignment is not working since the LHS of the assignment is also varying.
Error: ACTN_01_NM=VP-DTL-REC-CNT: not found
Its trying to execute this statement.

Can anyone suggest me how to do this using korn shell script, is it possible to use a varying value on LHS of assignment?

Quick help is appreciated.

It should definitely be easier if you explain what exactly you're trying to achieve.
Bare in mind that the pure shell is not the most appropriate tool for processing text files.

Instead of:

      1 ) ACTN_0${u}_NM=`echo $var|cut -d"," -f"$v"` ; exit ;;

try:

      1 ) eval ACTN_0${u}_NM='`echo $var|cut -d"," -f"$v"`' ; exit ;;

:b: Thanks alister, it worked fine for me.

radoulov, thanks for your input, i was just looking how i can use the value of one variable as a variable name.
