## value begining and ending with specific number

Hi!  I have a variable (concurrentcrg)..and I need to flag all the observations with values that start with 5 but do not end in 1.

Here the line of code that did not work...

if concurrentcrg in: ('5') and concurrentcrg ne '%1' then status='Uncontrolled';

Help is appreciated!

## Re: value begining and ending with specific number

If character field, look at the SUBSTR() function.

If numeric field look at the SUBSTRN() function.

The REVERSE() function will reverse a string so you can obtain the last character. Or you could use the LENGTH function to get the last character.

Since it looks character, consider using the reverse function.

if substr(char, 1,1) = '5' and substr(trim(reverse(char)), 1,1) ne '1' then status='Uncontrolled';

Is it a character or numeric field?

Assuming it's character, then:

data want;
set have;
if first(concurrentcrg) eq '5' and first(reverse(strip(concurrentcrg))) ne '1'
then status='Uncontrolled';
run;
