Macro variable value with percents

[kalbo]

hi, im trying to create a macro variable containing a search term such as %UNS%.

I will need to use this search term many times throughout the program.

For example:

%let searchterm=%UNS%;

data out;

set in (where=(visit like "&searchterm")) ;

run;

The problem is that the % is messing things up. How can I use such a macro variable?

[PaigeMiller]

%let searchterm=%nrstr(%%)UNS%nrstr(%%);

[Ksharp]

%let searchterm=%nrstr(  %F%  );



data out;
set sashelp.heart (where=(sex like "&searchterm")) ;
run;

Use %NRBQUOTE.

data have;
input visit $;
datalines;
%UNS%
%NO%
%HI%
;
run;

%let searchterm = %nrbquote(%UNS%);

%put &searchterm.;

data want;
set have (where = (visit like "&searchterm"));
run;

Obs visit 
1 %UNS%

Why not just include the quotes in the macro variable?  The macro processor ignores strings bounded on the outside by single quotes.

%let searchterm='%UNS%';
data out;
  set in (where=(visit like &searchterm )) ;
run;

Or use a different search method.

%let searchterm=UNS;
data out;
  set in (where=(index(visit,"&searchterm")) ;
run;

Tom,
Good idea. But That is not readable for some user .
