how to find a word in the variable in sas datastep

vraj1 — Thu, 03 Nov 2016 12:31:12 GMT

I have a dataset and in that a variable called var. In that i need extract observations which has a word "SOMETH". It may be first word or middle or last. Can you please explain me how to do it.

I tried var=:"SOMETH" but it only gives if the word comes first.

If it is a separate word, look at the findw function. If it may be part of a word, look at index.

Hello,

Sql Solution:

data have;
set sashelp.class;
if mod(_n_,4)=1 then name_new=cats(name)||'SOMETHetc etc';
else if mod(_n_,4)=2 then name_new=cats(name)||'SOMETHetc';
else if mod(_n_,4)=3 then name_new=name||'SOMETH';

Really?

You have

- a variable to search (var)

- a string to search for ('SOMETH')

So where's the problem?

data test;
var = 'This is a text with SOMETH in it';
result = findw(var,'SOMETH');
run;

proc print noobs; run;

Result:

              var                   result

This is a text with SOMETH in it      21

And if your value may sometimes have different case and you want to match "Someth", "someth" or even "someTH" as well as exactly "SOMETH" your comparison would need to consider case:

result = findw( upcase(var),'SOMETH')

Some actual concrete examples would help with input and desired result.

Note that your original search does not match "words".

See this example:

data example;
   informat str $15.;
   input str 1-15;
   if str =: 'SOMETH' then put "Found" Str=;
datalines;
SOMETH
SOMETHing
Someth ELSE
something 
;
run;

Use this function if your var has mixed case.

find(var,"SOMETH","i")
