Numbers stored as Char Variables & Their Magnitude

[apple]

I have

'1', '2', '3',... stored as a Character variable - Types

If i want to subset a dataset

if Types <='10'

will it select all values from '1',....'10'?

In other words, does SAS interpret the magnitude of numbers stored as character variable in the same way as  numeric variable?

Thank you

No it doesn't. It compares character by character. You need to convert your characters to numeric for such a comparison.

23 data _null_;
24 types='2';
25 if types<='10' then put 'TRUE';
26 else put 'FALSE';
27 
28 if input(types,best32.)<=10 then put 'TRUE';
29 else put 'FALSE';
30 
31 run;

FALSE
TRUE
