I've been using R for about 4 years now but am just beginning to use SAS. In R, given a data set called "data" with variables Y, X1, ..., Xp, I can call up a regression command in R:

lm(Y ~ ., data=data, ...)

Is there anything that corresponds to the function the period serves (i.e., calls in all the remaining variables) in SAS? Or do I need to explicitly write out all the variables I want included in the model? I've asked several people in person and none know how to do it. Thanks in advance.
