Scan function macro

Julia22 — Wed, 29 Nov 2017 01:11:23 GMT

I have

Note : XOP PM is one word and XOP DD is one word and X/Y/N is one word

%macro test;

%let xy= XOP PM , XOP DD, X/Y/N, EPP,ACC,ENN;

want to scan how many word I have

answer should be 6

%let n=%sysfunc(countw(%bquote(&xy)));

%do h=1 %to &n;

%let cname = %upcase(%scan(&xy,&h.,%str(',')));

%END;

%PUT &cname;

%mend;

%test;

So first time cname should be XOP PM and second time cname should be XOP DD and third time cname should be X/Y/N

Can u please help

Why are you specifying the delimiter for %SCAN() but not for COUNTW()?

Why are you quoting the commas in &XY for the COUNTW() function, but not for the %SCAN() function?

Why did you include single quote character in the list of delimiters? If they are valid delimiters then you can use ',' as the delimiter specification and you will not need to use macro quoting since the actual quotes will prevent SAS from thinking the comma is part of the function call.

%macro test;
%local xy n h cname ;
%let xy= XOP  PM , XOP DD, X/Y/N, EPP,ACC,ENN;
%let n=%sysfunc(countw(%bquote(&xy),%str(,)));

%do h=1 %to &n;
  %let cname = %scan(%qupcase(&xy),&h,%str(,));
  %put H=&h CNAME="&cname";
%end;

%mend test;

6881   %test;
H=1 CNAME="XOP  PM"
H=2 CNAME="XOP DD"
H=3 CNAME="X/Y/N"
H=4 CNAME="EPP"
H=5 CNAME="ACC"
H=6 CNAME="ENN"

Use COUNTC function

wordsn=sum(countc(sourcevar,","),1);

Then you can proceed with your code.
