Akshay,
I generally prefer making symbols for this kind of thing, as they give a 
bit more flexibility. So I would tend to do it like this:

  define symbol vname = `variable`
  LET/units="($vname)[d=2],RETURN=units`"/TITLE="`anomaly_title`" `anomaly_var` = `variable`_anomaly


Or, another solution is the SET ATTRIBUTE command. To have the new 
variable to inherit all the attributes of the old variable:

   let `anomaly_var` = `variable`_anomaly
   set att/like=`variable`[d=2]  `anomaly_var`
