Conditionally creating an Index

Hi. I'm trying to conditionally create an index, but only if it doesn't already exist. Can anyone help me with this? This attempt isn't working for me.

 

		data _null_;
			set sashelp.vmember (where=(Libname='WORK' and memname='FINALDATA%unquote(&zip5)'));
			if upcase(index) = 'NO' then do;
				PROC DATASETS;
				MODIFY FinalData%unquote(&zip5);
				INDEX CREATE imb_code /unique;
			end;
		RUN;

Re: Conditionally creating an Index

Well, this will give you a start, but I don't know what that macro variable is or why it is there at all:

data _null_;
  set sashelp.vmember (where=(Libname='WORK' and memname='FINALDATA%unquote(&zip5)'));
if upcase(index)='NO' then call execute('proc datasets; modify finaldata'||&zip5.||'; index create imb_code /unique; run; quit;'); run;

My 2 cents on this: this code will not create an index if any index exists. It is not specific to index imb_code. So there may still be room for improvement. But kudo's to the use of call execute(). Very underestimated and often misunderstood.
