Is there a way to use proc datasets and delete with certain conditions?
For example, I have dataset A and I want to delete if it the mean of one of its variables is less than a certain number. I have that mean stored in a macro variable.
I notice that it wont let me put a regular if statement in proc datasets. Is there another way to do this?
FYI, the reason I need to is I am creating hundreds of datasets with a do loop, and I only want the datasets stored if they are meeting a condition, or else too much room would be made up in the end.
If you are already using a macro then you can use conditional logic (%IF %THEN etc).
Or you can just generate the code and then execute it.
For example you might do what you want with PROC SQL ;
data x;
set sashelp.class;
run;
proc sql noprint ;
select case when (mean(age)<14) then 'proc delete data=x;run;'
else ' ' end
into :code
from x
;
quit;
&code;

Yea, thanks for the help, i feel dumb not thinking outside the box there.
