RATS Basics: Examining The Data We recommend that you examine data that you read in, just to make sure there are no problems with the data set or your program. This is especially important when you first start working with a particular data set. In our example program, we'll use the TABLE instruction, which displays some basic statistics on all the series currently in memory, and the PRINT instruction, which displays the actual values of the series. Our Example Program Here's our sample program, including the TABLE and PRINT instructions.
