You have to use quatition mark inorder to assign value to variable.

a='m';
b=a;

You can use INPUT function like below.

A=INPUT('12/10/2009',MMDDYY10.);

Partha,
Are you looking for this:

proc format;
value whatday 1='Sunday'
2='Monday'
3='Tuesday'
4='Wednesday'
5='Thursday'
6='Friday'
7='Saturday';

run;

data test;
a='12/18/2009';
b=input(a,mmddyy10.);
format b mmddyy10.;
c=weekday(b);
format c whatday.;
run;

If interested, consider a more standard approach using the SAS-supplied DOWNAME format to get the weekday name from a SAS DATE type variable.

are you talking "constants"?
a=2
assigns a constant to variable A.
"25dec2009"d
is a date constant
