I'm trying to quote a substring of a macro variable. The code is: %let hola=resuelto!;
%macro prueba(param);
%let amper=¶m;
%let amper2=%nrbquote(%substr(¶m,1,3));
%put ¶m;
%put &er;
%put &er2;
%mend;
%prueba(%nrstr(&hola)); In the log, I'm getting: WARNING: Apparent symbolic reference HO not resolved.
&hola
&hola
&ho The problem is I need to assign amper2 literally the value &ho , without any attempt of resolution, like I do with amper , that gets literally the string &hola ... any idea? Thank you in advance!
