Two options, if the index is same (8th 9th and 10th) and the required values are in the 2nd line

Code:
awk -F, 'NR==2{gsub(/\"/,x);print $8,$9,$10}' file.csv

More generic one would be similar to the one posted on the other thread Perl to shell script - The UNIX and Linux Forums

Code:
awk -F, 'NR==1{gsub(/\"/,x);for(i=1;i<=NF;i++){a[i]=$i;};getline;gsub(/\"/,x);for(i=1;i<=NF;i++){array[a[i]]=$i}} END{print array["IVALDATE"],array["IVALSTART"],array["IVALEND"]}' file.csv

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
