Yes you can create as many macro variables as possible.

I hear you talking about _N_ as the observation number.  However, _N_ is actually the number of times the code cycled to the DATA statement.

Try this code to see what I mean:

data new_class;

    set sashelp.class;

    if sex eq 'M' then return;

    x=_n_;

    output;
run;

proc print data=new_class; run;

the original class had 19 obs, new_class has only 9.

look at the values for x they are not the same as the obs number, but the number of times the code hit the DATA statement.

Just be crateful when referring to _N_ as the observation number.

This thread is about creating lists of macro variables

and this paper covers the various ways of handling such lists.
