删除SAS宏中的尾随空格

我想删除宏中变量的尾随空格,我尝试了TRIM、STRIP、%LET,但没有任何效果。我能得到帮助吗?

%MACRO DRY(count);
data _NULL_;
inpcount = "&count";
baseref1 = substr(jobid,4,2);   ------ value of the jobid is 75412
if inpcount < 10 then do;
   baseref = baseref2 || inpcount ;
end;
else do;
   baseref = baseref2 || inpcount ;
end;
call symputx('baseref',baseref,'g');
run;

%put baseref: &baseref;

---我得到的值为“SYMBOLGEN:宏变量BASEREF

resolves to 38   1
baseref: 38   01" 

预期结果应为baseref:3801
