How to create a macro variable into a macro function containing special characters

[alepage]

Hello,

I have tried the following code and it works.

But when I put it in a macro function, it failed.

The idea is to replace the " sign in the prolog from an xml file by %bquote(") to make sure that the macro variable has an acceptable structure.

%let prolog1=<?xml version="1.0" encoding="windows-1252" ?>;

%let target='"';

%let replacement=%bquote(");

%let prolog1=%sysfunc(tranwrd(%quote(&prolog1.),&target.,&replacement.));

%put &prolog1;

I would like to do the same thing but in a macro function such as:

%macro test;

%global gtarget greplacment gprolog;

%let prolog1=<?xml version="1.0" encoding="windows-1252" ?>;

%let target='"';

%let gtarget = &target.;

%let replacement=%bquote(");

%let greplacment= &replacement.;

%let prolog1=%sysfunc(tranwrd(%quote(&prolog1.),&target.,&replacement.));

%let gprolog=&prolog1.;

%mend test;

%test;

%put &gprolog.;

%put &greplacement.;

%put &gtarget.;

Corrected:

%macro test;

%global gtarget greplacement gprolog;

 

%let prolog1=<?xml version="1.0" encoding="windows-1252" ?>;

%let target='"';

%let gtarget = &target.;

%let replacement=%str(%");

%let greplacement=( &replacement.);

%let prolog1=%sysfunc(tranwrd(%quote(&prolog1.),&target.,( &replacement.)));

%let gprolog=&prolog1.;

 

%mend test;

%test;


%put &gprolog.;

%put &greplacement.;

%put &gtarget.;

That will not actual apply macro quoting to the quotes, since the use of %SYSFUNC() instead of %QSYSFUNC() will remove the macro quoting.

If you just want to quote the special characters in the input then use a regular macro quoting function.

%let prolog3=%superq(prolog1);

As you can see it this picture the value of PROLOG3 has macro quoting and the value of PROLOG1 and PROLOG2 don't.
