variable field column output search

[raffs]

I have a field separated list of variables embedded with an ksh script i.e

VX_VOL="vol01 vol02 vol03 vol04"

VX_VOL02="vol05 vol06"


how can display the last field column, since the variable list is variable in length ?

I can't grep the $4 or $2 since the variable list could be 1 or 100 in length.

Any help much appreciated.
