Hi friends,
I am facing problem in using cats in macro i.e
when i m using this [below] its giving me correct result[here value of &x is being vary by do loop]
%let jb= %qsysfunc(cats(&jb,%str(,),&x));
But when i try to use: %let jb= %sysfunc(cats(&jb,%str(|),&x));
In this case result is only last variable.
Can u please help me on this , I have solved by didnt use any function i.e : %let jb= &jb|&x;
But i m looking for solution with function.
This works fine for me:
%let jb=eee|bbb;
%let x=ccc;
%let jb= %sysfunc(cats(&jb,%str(|),&x));
%put &jb.;
=eee|bbb|ccc
Please supply and example with data as perhaps that is causing your issue (i.e. maybe quotes?).
data test;
input x $;
datalines;
a
b
c
d
e
f
g
;
run;
%let jb=;
data _null_;
set test;
if _n_=1 then; do;
call symput("x",x);
%let jb= %qsysfunc(cats(&jb,%str(,),&x));
end;
run;
%put &jb;
Ah, I see. You can't do the %let statement in datasteps like that. What you need is call symput, something like:
data test;
input x $;
datalines;
a
b
c
d
e
f
g
;
run;
data _null_;
attrib lstx format=$2000.;
set test end=last;
retain lstx;
if _n_=1 then lstx=x;
else lstx=strip(lstx)||","||strip(x);
if last then do;
call symput('jb',lstx);
end;
run;
%put &jb;
My apology for providing you not exact example, actually program and dataset is very large, I would like to try to provide a portion of programe where i m facing issue.
here jobno, is number of unique subject
jlist is list of subject ie X|Y|Z|......
jobmax is largest one..
in bold where i m facing issue.
%macro findjb();
%do i = 1 %to &jobno;
%let x= %scan(&jlist,&i,%str(|));
proc sort data = jobs_&jobmax; by hash state; run;
proc sort data = jobs_&x; by hash state; run;
data comb;
merge jobs_&jobmax(in=var1) jobs_&x(in=var2);
by hash state;
if var1=0 and var2=1;
run;
proc sql ;
select count(*) into :ctno from comb;
quit;
%put &ctno;
%if &z=1 and &ctno=0 %then %do;
%let jb= &x;
%let z=%eval(&z+1);
%put &jb;
%end;
%else %if &z ne 1 and &ctno =0 and &x ne &jobmax %then %do;
%let jb= %sysfunc(cats(&jb,%str(|),&x));
%put &jb;
%end;
%end;
%put &jb;
data finaljb;
set testjobs;
if jobboardid in (&jb);
run;
%mend findjb;
%findjb;
Mmm, having some difficulty following what you are trying to do there. May I suggest to add these couple of lines in:
---
%else %if &z ne 1 and &ctno =0 and &x ne &jobmax %then %do;
%put X: &x.;
%put JB: &jb.;
%let jb= %sysfunc(cats(&jb,%str(|),&x));
%put &jb;
%end;
---
And see what comes out - make sure to have moptions mprint and symbolgen on. It maybe something simple, perhaps try putting double quotes around the &x and &jb for instance = %sysfunc(cats("&jb.",%str(|),"&x."));
If you want to generate | delimited list of values from a dataset into a macro variable then PROC SQL can do that directly.
proc sql noprint ;
select jobid into :joblist separated by '|'
from mydata
;
quit;
Why would you be using CATS() function with macro variables?
