The Verticle Vs The Horizontal......

a: The sas data step ~
b: cargo manifest for a freight train

What: Visually and logically, the SAS data step is read vertically, from the top to the bottom. But the vertical syntax is processing something, the PDV, that could be though of as being a horizontal row of variables. What is this like? A vertical process conjoined to a horizontal process? How about the cargo list of a freight train with 10 cars. The cargo list if a vertical sequence of car numbers and their contents. When you go to look at the train, it is a define horizontal entity with each entity having a specific place in the train and with each entity having specific contents.
