Understanding the SAS/IML Language: Control Statements

Control Statements

The SAS/IML language has statements that control program execution. You can use control statements to direct the execution of your program and to define DO groups and modules. Some control statements are shown in the following table:

Table 3.1 Control Statements
Statement	Description
DO, END	Specifies a group of statements
Iterative DO, END	Defines an iteration loop
GOTO, LINK	Specifies the next program statement to be executed
IF-THEN/ELSE	Conditionally routes execution
PAUSE	Instructs a module to pause during execution
QUIT	Exits from the IML procedure
RESUME	Instructs a module to resume execution
RETURN	Returns from a LINK statement or module
RUN	Executes a module
START, FINISH	Defines a module
STOP, ABORT	Stops the execution of an IML program

See Chapter 6, Programming Statements, for more information about control statements.
