Assign the values to a macro variable

SASdevAnneMarie — Sat, 11 Jan 2025 10:44:22 GMT

Hello Experts,

Do you know, please, how to assign the multiple values (C1','C2') to te macro variables ?

%macro my_analysis(liste=,nom_part=);

	data base_finale_&nom_part.;
		set base_finale_0;

		if Trimestre="T1" and cd_code in(&liste.);
		keep PM PS PL;
	run;

	proc sort data=base_finale_&nom_part. nodupkey;
		by _all_;
	run;

	proc sql noprint;
		select sum(PL) 
			into :Montant_T1_&nom_part.  
				from base_finale_&nom_part.;
	quit;

	%PUT &&Montant_T1_&nom_part.;

	Data Finale_index;
		Montant_T1_&nom_part.=&&Montant_T1_&nom_part.;
	run;

%mend;

%my_analysis(liste='C1','C2',nom_part="PXXX");

Thank you !

Hello @SASdevAnneMarie,

Use blanks to separate the items in macro variable liste. The IN operator doesn't need commas and the macro processor doesn't like them.

Also omit the quotation marks around the value of nom_part because they are invalid characters in the name of a dataset or (macro) variable.

%my_analysis(liste='C1' 'C2',nom_part=PXXX)

Another thought to save typing the quotes and avoid the potential of making mistakes when you type the quotes: You can use the %QLIST macro to take your input string in &liste that does not have quotes, and create a new macro variable with single quotes around each item in &liste.

https://github.com/sasutils/macros/blob/master/qlist.sas

So, it would look like this:

filename qlist url 'https://raw.githubusercontent.com/sasutils/macros/master/qlist.sas';
%include  qlist;

%macro my_analysis(liste=,nom_part=);

	data base_finale_&nom_part.;
		set base_finale_0;
		if Trimestre="T1" and cd_code in %qlist(&liste.,comma=0);
		keep PM PS PL;
	run;

/* Other code */

%mend;

%my_analysis(liste=C1 C2,nom_part=PXXX)

If you have only two elements in &LISTE like C1 C2, this code really doesn't save you much typing; if the are 12 elements in &LISTE, this code becomes very helpful, a lot less typing and virtually eliminates the potential of typographical errors when you type the quotes.

NOTE: the filename statement may not work behind some corporate firewalls, in which case you then have to download the QLIST macro as a .SAS program and save it on your hard drive and then %include that file.

You can also use parentheses around the value being passed to protect the comma.

That can work in some places. The IN operator in a data step does not care if there are extra () in the list.

1    %let name=('Alfred','Jane');
2    data want;
3      set sashelp.class;
4      if name in (&name);
5    run;

NOTE: There were 19 observations read from the data set SASHELP.CLASS.
NOTE: The data set WORK.WANT has 2 observations and 5 variables.
NOTE: DATA statement used (Total process time):
      real time           0.00 seconds
      cpu time            0.01 seconds

Extra () do not cause trouble in list of initial values of ARRAY statements either.

But in SQL (and by extension a WHERE statement anywhere) it is more persnickety about it.

6    proc print data=sashelp.class;
7      where name in (&name);
                           -

You could use FINDW() function to replace IN operator:

%macro my_analysis(liste=,nom_part=);

	data base_finale_&nom_part.;
		set base_finale_0;

		if Trimestre="T1" and findw("&liste.",  strip(cd_code) ,' ','it' );
		keep PM PS PL;
	run;

	proc sort data=base_finale_&nom_part. nodupkey;
		by _all_;
	run;

	proc sql noprint;
		select sum(PL) 
			into :Montant_T1_&nom_part.  
				from base_finale_&nom_part.;
	quit;

	%PUT &&Montant_T1_&nom_part.;

	Data Finale_index;
		Montant_T1_&nom_part.=&&Montant_T1_&nom_part.;
	run;

%mend;

%my_analysis(liste=  C1  C2 ,nom_part="PXXX");
