In a data step, here is the code:

var=(var>0);

What does it do

Assigns a boolean value to var, if var>0.

would be comparable to writing:

var=1234;

if var>0 then var=1;

else var=0;

now, var=1 instead of 1234.

One caution using this coding involve less than and missing. If you have a missing value it is always less than anything else. So if you do not want to assign or recode if the value is actually missing you need to include that condition:

If var ne . then var= (var<10);

for example.
