I want to create a date variable in my program from a macro %LET statement.
%LET date9 01AUG2017;
data new;
set old;
date = &date9;
run;
I cant get this to work, I dont quite understand how the date9 is stored in SAS I think - adding a format statement also doesnt work. What am I missing here?
Try
data new; set old; date = "&date9"d; format date date9.; run;
You were attempting to use a "date literal" value but missing that in basic syntax the way to use a data literal is "01JAN2017"d; The d at the end, no space after the quote, tells SAS to use this a date. Date literal must be in the form of ddMONyy or ddMONyyyy where dd is day of month, MON is three-letter abbreviation and yy or yyyy is either a 2 or 4 digit year. I recomment using the 4-digit to remove any confusion.

Same suggestion as @ballardw, but you'll also have to correct your let statement:
%LET date9=01AUG2017; data old; input x y; cards; 1 2 3 4 ; data new; set old; format date date9.; date = input("&date9",date9.); run;

Thank you both! LET statement was a typo, both worked beautifully.
And if you want today, you can use DATE() or TODAY()
*Create a macro variable;
%let myDate = %sysfunc(today(), date9.);
*Display macro variable for testing;
%put &myDate;
Hi, I noticed you have missed out an = sign in a %let statement. %let is a macro assignment statement just like a variable assignment statement in a datastep.
Secondly you can copy paste @ballardw solution
Correction:
%LET date9=01AUG2017;
