st: RE: sub-dataset by variable numbers
Dear all
Many thanks indeed for those who has answered my question. Sebastian B�chte has suggested a better way which solved my problem perfectly :
unab vlist : _all
//keep 3rd to 6th variable from dataset in memory keep `: word 3 of `vlist'' - `: word 6 of `vlist''
Thanks Sebastian!
Regards
Jianan
