Hello,
I have got a list of words and I would like get these words with double quotes.
%let list_have = word1 word2 word3 ...; the max number of word is 10
I would like to get the macro variable list_want that would contain "word1" "word2" "word3" ...
thanks in advance for your help
regards
Nasser
Really not the best idea to be using a text find and replace system for data. You can do it simply (shows the power of using the real programming language rather than find/replace) in a data _null_;
%let list_have = word1 word2 word3;
data _null_; length temp $2000; temp=cat('"',tranwrd("&list_have."," ",'" "'),'"'); call symput('list_want',temp); run;
%put &list_want.;
You can likely do the same if you create some ghastly complex macro code which is indecipherable and falls over every other run.

Within a macro you can also use the following which allows direct assignment in a let statement. This is adapted from http://documentation.sas.com/?docsetId=mcrolref&docsetTarget=p1n2i0ewaj1zian1ria5579z1zjh.htm&docset...
%let list_have = word1 word2 word3;
%macro quotelist(varlist);
%let word_cnt=%sysfunc(countw(&varlist));
%let list=;
%do i = 1 %to &word_cnt;
%let temp=%qscan(%bquote(&varlist),&i);
%let list = &list %bquote("&temp.");
%end;
&list;
%mend;
%let new = %quotelist(&list_have);
%put &=new;
@foobarbaz I reached a similar result. However note the difference in behavior with:
%macro addquote (wordlist); /* word list is expected to be space delimited and no word containing quotes or special symbols*/ %let result=; %do i=1 %to %sysfunc(countw(&wordlist)); %let result = &result %sysfunc(quote(%sysfunc(scan(&wordlist,&i)))); %end; &result %mend; %put %addquote(var1 var2 var3); data junk; set sashelp.class; where name in (%addquote(Alice Carol John Philip)); run;
and
data junk; set sashelp.class; where name in (%quotelist(Alice Carol John Philip)); run;
Hello,
%let list_have=word1 word2 word3;
%let want="%sysfunc(tranwrd(&list_have.,%str( ),%str(%" %")))";
%put &want.;
%let list_have = word1 word2 word3;
%let list="%sysfunc(prxchange(s/\s+/" "/,-1,&list_have))";
%put &list ;
I'm a big fan of Richard DeVenezia's utility macro %SepList. It does a lot of list management, including adding quotes to items, changing delimiters, adding prefixes...

83 %let list_have = word1 word2 word3 ; 84 85 %put %seplist(&list_have,indlm=%str( ),dlm=%str( ),nest=QQ) ; "word1" "word2" "word3" 86 87 %put %seplist(&list_have,indlm=%str( ),dlm=%str( ),nest=Q) ; 'word1' 'word2' 'word3' 88 89 %put %seplist(&list_have,indlm=%str( ),dlm=|) ; word1|word2|word3 90 91 %put %seplist(&list_have,indlm=%str( ),dlm=%str(, ),prefix=_) ; _word1, _word2, _word3
I changed my personal version slightly, so that it %unquotes the value returned, and the default value for DLM is set to INDLM.
I am big fan of PRXCHANGE for this kind of problem which is origined from @Patrick
