Check if first character in the string can be numeric, then convert them

[vietlinh12hoa]

I have 2 strings string 1 = '1st' and string 2 = 'Super'

I want to have new variable to check if the first character is numeric then convert to number, else empty, like:

new string 1 = 1

new string 2 = .

In Python it's super easy, not sure how to do that in this programming style.

Hello @vietlinh12hoa,

Try this:

data have;
input string $;
cards;
1st
Super
;

data want;
set have;
number=input(string, ?? 1.);
run;
