Delete obsvations with certain strings

Xiaoningdemao — Tue, 14 Jun 2016 21:49:05 GMT

Hi all,

Say I have the following observations:

fruit

apple

apple comments

pear

pear comment

banan

I want to delete those have 'comments' and 'comment'.

I wrote code as

data mock; set mock0; run;
data mock;
modify mock;
where fruit contains 'comment' and 'comments';
remove;
run;

But it doesn't remove those with 'comments'. Can I do thses two select at once?

Thanks alot!

where fruit contains 'comment' or fruit contains 'comments';

If you are going to create a new dataset anyway, you might as well filter as you copy:

data mock;
set mock0;
where not (fruit contains "comment" or fruit contains "comments");
run;

Would:

data mock;
  set mock0;
  where index(fruit,"comment")=0;
run;

Not be simpler?
