Hi,

I have a long macro variable (check) and need to scan  the presence of a word  using a macro and in a data step ? How can I do that?

 

%let check=This is Year 2017, Month 12, Day 12;

data a;
var= "Month";
run;

A slight change accomplishes this:

 

if findw("&string", trim(var), ',') > 0 then flag=1;

 

This change tells the function to use commas as the only delimiters.  Note that this fails if the original macro variable contains blanks after the commas.

Can you please elaborate the task that you want to accomplish?

The safest tool is probably the FINDW function:

 

%let check=This is Year 2017, Month 12, Day 12;

data test;

var="Month";

if findw("&check", var) > 0 then flag=1;

else flag=0;

run;

 

You might want to consider whether upper vs. lower case matters:

 

if findw(upcase("&check"), upcase(var)) > 0 then flag=1;

Thanks for your reply.  I should have posted bit more clearly. How do we flag here? Need to get the third one flagged.


%let string=MONTH 1-ABC MONTH 0,MONTH 1-ABC MONTH 2,MONTH 1-ABC MONTH 3,MONTH 1-ABC MONTH 3,MONTH 5-ABC MONTH 6;
%put &=string;

 

data test;
length var $100;
var="MONTH"; output;
var="MONTH 1-ABC MONTH 1"; output;
var="MONTH 1-ABC MONTH 2"; output;
var="MONTH 1-ABC MONTH 8"; output;
run;

data test;
set test;
if findw("&string", var) > 0 then flag=1;
else flag=0;

run;
