delete rows when a variable contain a string

[sasphd]

I want to delete rows when a variable name contain a string (INFRA)

have 

id name 

1 don infra

2 waw 

3 sik infra

4 dfh

want 

id name

2 waw 

4 dfh

Does "infra" vs. "INFRA" make a difference?  One possibility:

data want;

set have;

if index(upcase(name), "INFRA") = 0;

run;

No it does not matter. 

however the program does not work. what I want is to delete rows containing the string "infra"

So why do you say it does not work?

[novinosrin · Accepted solution]

data have;
input id name & $20.;
cards;
1 don infra
2 waw 
3 sik infra
4 dfh
;

data want;
set have;
if not ^^find(name,'infra','i');
run;

Or with FINDW

data have;
input id name & $20.;
cards;
1 don infra
2 waw 
3 sik infra
4 dfh
;

data want;
set have;
if not ^^findw(name,'infra',' ','i');
run;
