Looping is the first step that a programming beginner learns. Printer-friendly version Introduction When programming, you can find yourself needing to tell SAS to execute the same statements over and over again. Stay updated with the latest technology trends while you're on the move - Join DataFlair's Telegram Channel. Eberly College of Science. In this case, the general form of the iterative DO loop looks like this:. When programming, you can find yourself needing to tell SAS to execute the same statements over and over again. Other DO specifications exit after tests are performed at the top or bottom of a loop. The other thing you might want to notice about the DATA step is that there is no input data set or input data file. Eberly College of Science.

    Iterative DO loops are the simplest form of DO loops that can be executed within a SAS Data Step. The actions of an iterative DO loop are unconditional. A basic iterative DO statement in the SAS/IML language has exactly the same syntax as in the DATA step, as shown in the following PROC IML. The DO UNTIL statement executes a group of statements repetitively until the condition that you specify is true.

    The condition is checked after each iteration of.
    The value of the variable matrix is initialized to the value of the start matrix. In this lesson, we'll explore the ins and outs of these three different kinds of loops, as well as take a look at lots of examples in which they are used.

    Here's what a simple iterative DO loop should look like:. We call those kinds of loops iterative DO loops.

    The index variable equals the value of the current item. The data values are read one at a time into the scalar variables Namexand y.

    Let us understand SAS Loop with some example.

    In conclusion, we think these were similar to the loops you learned in other languages, and easier too. To list items in a series, you must specify.

    Do you have any additional comments or suggestions regarding SAS documentation The iterative DO statement executes a group of statements several times.

    The DO statement supports clauses that iterate over compound statements. With an iterative DO statement, you can repeatedly execute a set of statements until. In this section, we'll explore the use of iterative DO loops, in which you tell SAS to execute a statement or a group of statements a certain number of times.
    The following program uses an iterative DO loop to tell SAS to determine the multiples of 5 up to After having initialized answer to 0, add 3 to answerthen add 3 to answer again, and add 3 to answer again, and add 3 to answer again.

    Printer-friendly version Introduction When programming, you can find yourself needing to tell SAS to execute the same statements over and over again. Sometimes we will want to stop iterating if a certain condition is met. The loop ends when the value of i is greater than

    We call those kinds of loops iterative DO loops. Here, we override the automatic output by explicitly telling SAS to output the value of the multiple variable every time that SAS adds 5 to it. Note that if the expression is false the first time it is evaluated, the loop is not executed. In this case, the general form of the iterative DO loop looks like this:.

    1. In conclusion, we think these were similar to the loops you learned in other languages, and easier too. We are generating data from scratch here, rather than from some input source.

    2. The other thing you might want to notice about the DATA step is that there is no input data set or input data file. Upload the file to the Lesson 18 Homework Dropbox.

    3. This value is then incremented by the increment value or by 1 if increment is not specified until it is greater than or equal to the stop value.
