How to create a macro var that repeat a word n times

Macro — Mon, 13 Oct 2014 23:07:57 GMT

I would like to create a macro varialbe which contains repeated '$my_p' 100 times separated by space, the output should look like $my_P $my_p $my_P

I use the following, but it is not separated by space though

%let my_format=%sysfunc(repeat($my_P ,3));

%put my_format=&my_format;

Result:

my_format=$my_P$my_P$my_P$my_P

How to make this work, and any other ways?

add a space to your macro variable?

%let my_format=%sysfunc(repeat(%str( )$my_P ,3));

%put my_format=&my_format;

Hello,

A macro solution:

%macro a(concvar, reptimes);

%global resvar;
%let resvar=;

%do i=1 %to &reptimes;
%let resvar=&concvar &resvar;
%end;

%mend a;

%a($my_P, 5)
