I figure he either ment Delineated or Delimited (in this case delimited by a
SPACE) And personally, I would have done it:

list=3D'1 5 7 22'

for value in ${list}
do
  echo ${value}
done

Then, at some time in the future, you can replace the setting of 'list' with
anything from
a call to a function of some type or even a call to a database.

It is a stupid way to set multiple variables from a deliminated list. Smart way would be this:

$ let A=3D2;
$ let B=3D3
$ let C=3D$A*$B
$ echo $C

6
$ echo $SHELL
/bin/ksh
$
