doesn't work in my sas9.1.3

192  data ps2004dic;
193  set  ps2004 ;
194  if q: ~=. then q: = 0< q: <3;
         -
         388
         76
           --
           200
ERROR 388-185: Expecting an arithmetic operator.

195  run;

was stopped there were
         0 observations and 79 variables.

Interesting that it got as far as thinking it had started running
