find out variable contains only numeric

sunilreddy — Mon, 18 Mar 2013 21:19:31 GMT

Any way to find out the variables contains only digits(0 to 9)

data have;

input var $;

cards;

23,32

12.32

32 42

23ab

$23

123

;

run;

I want only last record(var=123) in target table, which doesn't have any alphabetic or special characters. Also i want to throw it to error table for remaining records(1 to 5 records in above example)

The way you are creating your input file will get you the wrong results. You have to add an ampersand on your input statement.

However, that said, try the following:

data have;

input var $ &;

cards;

23,32

12.32

32 42

23ab

$23

123

;

run;

data want errors;

set have;

if notdigit(strip(var)) then output errors;

else output want;

run;
