Akbar,
Here is a way to create a macro flag for the use of an index and and more.
Data test( index=(x) ) ;
Do i=1 to 15 ;
x = ceil( ranUni(159753) * 9999 ) ;
Output ;
End ;
Run ;
Proc contents
data=test
out=idx( keep= name idxCount idxUsage )
noPrint
;
Run ;
Data _null_ ;
Set idx ;
If ( _n_ eq 1 ) then
call symPut( "index" , put( idxCount , 3.-L ) )
;
If ( idxUsage ne "NONE" ) then
call symput( "indexOn" || trim(name) , idxUsage )
;
Run ;
%put _user_ ;

Subject: Macro Variable
Q? I made a data set with Index. Is there a macro variable to indicate such
a data set has an index? Or is there a way to crate the macro variable?
Thanks.
