A warning of missing the END of DO group

[supmilk]

Hey guys,

Sas shows me a waring that Do group statements were not executed due to missing END at the time of Quit,

BUT although I have checked it for several times, I still cannot find the problem. 

proc iml;
load D;
load RR;
load LL;

start LLH(st,fi,S);
 b_1=(S[st:(fi-1),4]`)*S[(st+1):fi,4]/((S[st:(fi-1),4]`)*S[st:(fi-1),4]);
 b_2s=S[(st+1):fi,4]-b_1*S[st:(fi-1),4];
 b_2=b_2s[:];
 sigma_s1=S[(st+1):fi,4]-b_1*S[st:(fi-1),4]-b_2;
 sigma_s2=sigma_s1##J((fi-st),1,2);
 sigma=(fi-st-1)/(fi-st-2)*sigma_s2[:];
 if sigma=0 then LLF=.;
  else do;
  LLF=(-0.5*(fi-st-1))*log(2*arcos(-1)*sigma)-1/(2*sigma)*((S[st:(fi-1),4]`)*S[st:(fi-1),4]);
 end;
return(LLF);
finish LLH;

fname = "split1":"split2320";
do i = 1 to ncol(fname);
 dsname = "spl1." + strip(fname[i]);
 use (dsname);
 do t=1 to 120;
  g=D[t,1];
  read all where(COL2=g) into SS; 
  if nrow(SS)=0 then RR[i,t]=.;
   else do;
   st=1;
   fi=15;
   M_sf=J(1,2,0);
   do until (fi>240);
    if abs(LLH(st,fi+1,SS)/LLH(st,fi,SS)-1)>0.1 
     then do;
     M_sf[1,1]=st;
     M_sf[1,2]=fi;
     stfi=stfi//M_sf;
     st=fi+1;
     fi=fi+15;
     if st>225 
      then do;
      M_sf[1,1]=st;
      M_sf[1,2]=240;
      stfi=stfi//M_sf;
     end;
     else do;
     fi=fi+1;
     if fi>240 
      then do;
      M_sf[1,1]=st;
      M_sf[1,2]=240;
      stfi=stfi//M_sf;
     end;
    end;
   end; 
   do tt=1 to nrow(stfi);
    b_1=(S[st:(fi-1),4]`)*S[(st+1):fi,4]/((S[st:(fi-1),4]`)*S[st:(fi-1),4]);
    b_2s=S[(st+1):fi,4]-b_1*S[st:(fi-1),4];
    b_2=b_2s[:];
    sigma_s1=S[(st+1):fi,4]-b_1*S[st:(fi-1),4]-b_2;
    sigma_s2=sigma_s1##J((fi-st),1,2);
    r_11=sigma_s2;
    r_1=r_1+r_11;
    r_22=((S[(st+1):fi,4]-S[(st+1):fi,4][:])`)*(S[(st+1):fi,4]-S[(st+1):fi,4][:]);
    r_2=r_2+r_22;
   end;
   RR[i,t]=r_1/r_2;
  end;
 end;
 close;
end;

store RR;
create ba.RR from RR;
append from RR;
quit;

Post your full log. 

The included code shows 10 do's and 10 end's so the counts match, but I didn't read each line. 

I (SAS) formatted your code, which is what I usually do to try and find missing do/end. 

What type of SAS interface are you working with? In EG and Base there are keyboard shortcuts that allow you to jump from a Do to the corresponding END. I can't find a similar function in SAS Studio 😞

the full log is shown as:

.......(same as the code)

I use the base of SAS interface, and what is the keyboard shortcuts for the corresponding END of the DO group?

Thank you.

[Rick_SAS]

It looks like there is not an END statement for 

do i=1 to ncol(fname);

Put an END either before the STORE statement or before the QUIT, depending upon the logic of your program.

[supmilk]

Hi Rick,

Have you got the keyboard shortcuts for finding the END corresponding to the DO group, which is mentioned by Reeza?

Thanks a lot!

See Chris's blog on keyboard shortcuts.

Hi Rick,

I found that some problem still exists. The shortcut cannot lead to the right END with its corresponding DO group. Show you some example as below:

I start the shortcut at line 4, and sas jumps to line 9(wrong). I don't know why.

proc iml;
k=0;
t=0;
do f=1 to 3; /*start the shortcut here*/
if k=0 
then do;
k=k+1;
t=t+1;
end; /*but move to this wrong place*/
else do;
k=k+2;
t=t+2;
end;
end; 
print k t;
quit;
