It is not a "Class Method", it is just using a class statement in your procedure. So, if you have a categorical variable, you list it in the class statement to inform SAS that the variable is not continuous. You use the class statement in many procedures. See below for an example:

Once you start examing the syntax used in SAS, you will see the class statement used all over the place.

So I am a bit confused as to how to predict y using "Monday". Could I instead setup dummy variables in my model.In other words, each day of the week is either true or false variable. So instead of 1-7 for the day variable I would have 7 variables representing each day of the week.
If X=
Monday:1+0+0+0+0+0+0
Tuesday: 0+1+0+0+0+0+0
Wednesday: 0+0+1+0+0+0+0
etc...
I am trying to use the day of the week to determine the willingness to pay for a product. Does the market's willingness to pay increase or decrease for any given day of the week.
Willingness to pay$ = mon+tue+wed+thu+fri+sat+sun
If X=
Monday:1+0+0+0+0+0+0
Tuesday: 0+1+0+0+0+0+0
Wednesday: 0+0+1+0+0+0+0
etc...
