It is not a bit strange to assume external resources in the config file.
E.g. use $line, hoping that $line exists in the calling script.
If you really want that, you should put the per-line code in a function
Code:
file="/home/CSV/data.csv"file="bad"
badfile="/home/CSV/bad/"
runcode(){
num_fields=`echo "$line" | awk -F'|' '{print NF}'`
field1=`echo "$line" | awk -F'|' '{print $1}'`
}

and
Code:
. ./config.cfg
while IFS= read -r line
do
        runcode
        echo $num_fields
        echo "$field1"
done <"$file"

@rbatte1, the shell split differs from awk: a last empty field is not counted, $num_fields differs then.
Further, your code needs the delimiter
Code:
   IFS="|" my_array=($line)

and protection from argument expansion with
Code:
set -f

If the positional parameters can be used then there is no need for an array, and this works even with old Bourne shells
Code:
set -f
oIFS=$IFS; IFS="|"
while read -r line
do
   set -- $line
   echo "number of fields $#"
   echo "First field $1"
done <"$file"
set +f
IFS=$oIFS

LEARN ABOUT FREEBSD

boot.config

BOOT.CONFIG(5)						      BSD File Formats Manual						    BOOT.CONFIG(5)

NAME

     boot.config -- Configuration file for the boot blocks

DESCRIPTION

     The boot.config file contains options for the FreeBSD boot block code.

     When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are
     missing an ``a'' partition require user intervention during the boot process).  If the boot.config file is found, its contents are used as
     the default configuration options for the boot block code and are echoed to the system console.

     A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other
     valid boot(8) option on a single line, as it is done at the ``boot:'' prompt.

     The options related to the boot image selection described below and all the other options available for boot.config are documented in detail
     in the boot(8) manual page.

FILES

     /boot.config  parameters for the boot blocks (optional)

EXAMPLES

     The command:

	   # echo "-P" > /boot.config

     will activate the serial console of FreeBSD.

     The command:

	   # echo "1:ad(1,a)/boot/loader" > /boot.config

     will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk.

     The command:

	   # echo "1:ad(1,a)/boot/loader -P" > /boot.config

     will do both of the above.

SEE ALSO

     boot(8), loader(8)
