How do you end a DO loop in SAS?

How do you end a DO loop in SAS?

The LEAVE statement in the SAS DATA step is equivalent to the “break” statement. It provides a way to immediately exit from an iterative loop. The CONTINUE statements in the SAS DATA step skips over any remaining statements in the body of a loop and starts the next iteration.

DO loop by in SAS?

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, meaning that if you define a loop to execute 50 times, it will execute 50 times without stopping (unless an error occurs during processing).

What is SAS leave?

The LEAVE statement causes processing of the current loop to end. The CONTINUE statement stops the processing of the current iteration of a loop and resumes with the next iteration. You can use the LEAVE statement in a DO loop or in a SELECT group. You can use the CONTINUE statement only in a DO loop.

DO loop continue SAS?

The CONTINUE statement stops processing the current iteration of a loop and resumes with the next iteration. The LEAVE statement causes processing of the current loop to end. You can use the CONTINUE statement only in a DO loop. You can use the LEAVE statement in a DO loop or a SELECT group.

Do repetitions do until statements?

In most computer programming languages, a do while loop is a control flow statement that executes a block of code at least once, and then either repeatedly executes the block, or stops executing it, depending on a given boolean condition at the end of the block.

Does bash do until loop?

The until loop is used to execute a given set of commands as long as the given condition evaluates to false. The condition is evaluated before executing the commands. If the condition evaluates to false, commands are executed.

What is end statement SAS?

The END= last option tells SAS to create a temporary numeric variable called last , which is initialized to 0 and set to 1 only when the SET statement reads the last observation in the input data set. The variable is temporary in that it is placed in the program data vector but not written to the output data set.

What is do in SAS?

What does the if last statement in SAS mean?

if last; is the statement that tells SAS to include in the output data set only the last observation in the input data set. The DROP statement tells SAS to drop the then meaningless Store, Dept, Quarter, and Sales variables from the output data set.

After SAS has added 3 to the answer variable four times, SAS exits the DO loop, and since that’s the end of the DATA step, SAS moves onto the next procedure and prints the result. The other thing you might want to notice about the DATA step is that there is no input data set or input data file.

What does the DROP statement do in SAS?

The DROP statement tells SAS to drop the then meaningless Store, Dept, Quarter, and Sales variables from the output data set. If you haven’t already done so, download the sales data set, and save it to a convenient location on your computer.

Is the name of the variable in SAS temporary?

Although we used the variable name last here, we could have used any valid SAS variable name. The variable is temporary in that it is placed in the program data vector but not written to the output data set.
