Filtering record with ASCII character

chee154 — Fri, 07 Feb 2020 06:26:51 GMT

Hello,

Trying to load in data via INFILE and then create a new logical column. However, if my data contains ASCII characters (ex. ">", "-") I'm trying to filter on, I don't think SAS is reading it. For example,

dataset =

(Toyota, 35000, >12)

(Toyota, 40000, 12)

data car;
infile 'file path.csv'
input Car $ Miles Group $; 
if Group = >12 then NewColumn = "a";
if Group = 12 then NewColumn "b";
run;

Expectation:

(Toyota, 35000, >12, a)

(Toyota, 40000, 12, b)

Results:

(Toyota, 35000, >12, )

(Toyota, 40000, 12, a)

Can someone help explain this, been reading on character comparisons but not much describes how to handle these operations... Thanks!

When comparing strings you have to enclose values in quotes. Try:

if Group = ">12" then NewColumn = "a";
if Group = "12" then NewColumn "b";
