an array can hold only numeric values, or only character values, like [pre]
* presuming large table is addressable as large.dataSet;
data results ;

set large.dataSet ;

array thisC(*) _character_ ;
array thisN(*) _numeric_ ;

do col= 1 to dim( thisC ) ;
this_name = vname( thisC(col) );

* process character columns ;


do col= 1 to dim( thisN ) ;
this_name = vname( thisN(col) );

* process numeric columns ;


run; [/pre]

Good Luck

it is great to know this Peter, I was not ware of this function.
what I was actually trying to do is to subtract each column, my data set is lik this

cus_id Bal_1 Bal_2 ... Bal_500
1 10 15 .... 50

and I would like to subtract Bal_2 - Bal_1 as Net_Growth1 , then Bal_3 - Bal_2 as Net_Growth2 and so on, if I could do it in an array it is great.
