As it has been shown by data _null_, your problem is can be replicated only
under certain special circumstances. One other way that this could happen
is with a length of $1 for parameter and then a leading space with the
assignment " 1011" ;

data a ;
 sample = 298 ;
 parameter = " " ;
run ;

data b ;
 set a ;
 if sample = 298 then parameter = " 1101" ;
run ;

options nocenter ;
proc print ;
run ;

Obs    sample    parameter

 1       298
