How to change a variable from Character to numeric without changing it's format

[Abhinav26]

DATA ONE;
INPUT
@001 NAME $10.
@011 MONTH $CHAR8.
;
cards;
Thomas 2017-01
Ricky 2018-09
;
run;

data two;
set one;
month_1 = input(month,yymmd.);
run;

I want output in which variable month_1 will be numeric in nature and format is going to be like 2017-01.
