proc contents in sas

Proc contents in SAS is a procedure that allows you to list out the contents of a data set. It provides a summary of the data set including the name of each variable and the type of data it contains. For example, if you had a data set with variables called “height” and “weight” the proc contents would tell you that “height” contains numeric data and “weight” contains numeric data. It’s like when you look inside a box and see all the items it contains. Proc contents lets you peek inside the data set and see what is inside it. Fun fact: The proc contents procedure was first introduced in the 1970s!
