Your read command is backwards -
Code:
echo "${TEMPFILE:14:2}  ${TEMPFILE:16:3} ${TEMPFILE:19:4}" | read a b c

IFS sets the record separator for a read, by default it is space(s). This means the first text block gets put in a, second in b, third in the c variable.

You can also create arrays like that:
Code:
#!/bin/ksh
set -A arr ${TEMPFILE:14:2}  ${TEMPFILE:16:3} ${TEMPFILE:19:4}
echo ${arr[0]}
echo ${arr[1]}
echo ${arr[2]}

bash uses declare -a arrayname value1 value2 ... valuen
plus you can assign values directly to each element of an array.
