If you specify no argument, the ABORT
statement produces these results under the following methods of operation:
- batch mode and noninteractive mode
-
- stops processing the current DATA step and writes
an error message to the SAS log. Data sets can contain an incomplete number
of observations or no observations, depending on when SAS encountered the
ABORT statement.
- sets the OBS= system option to 0.
- continues limited processing of the remainder
of the SAS job, including executing macro statements, executing system options
statements, and syntax checking of program statements.
- creates output data sets for subsequent DATA and
PROC steps with no observations.
- windowing environment
-
- stops processing the current DATA step
- creates a data set that contains the
observations
that are processed before the ABORT statement is encountered
- prints a message to the log that an ABORT statement
terminated the DATA step
- continues processing any DATA or PROC steps that
follow the ABORT statement.
- interactive line mode
- stops processing the current DATA step.
Any further DATA steps or procedures execute normally.
-
ABEND
- causes abnormal termination of the current
SAS job or session. Results depend on the method of operation:
- batch mode and noninteractive mode
- stops
processing immediately
- sends an error message to the SAS log that states
that execution was terminated by the ABEND option of the ABORT statement
- does not execute any subsequent statements or
check syntax
- returns control to the operating environment;
further action is based on how your operating environment and your site treat
jobs that end abnormally.
- windowing environment and interactive line mode
- causes
your windowing environment and interactive
line mode to stop processing immediately and return you to your operating
environment.
-
RETURN
- causes the immediate normal termination
of the current SAS job or session. Results depend on the method of operation:
- batch mode and noninteractive mode
- stops processing immediately
- sends an error message to the SAS log stating
that execution was terminated by the RETURN option of the ABORT statement
- does not execute any subsequent statements or
check syntax
- returns control to your operating environment
with a condition code indicating an error
- windowing environment and interactive line
mode
- causes your windowing environment and interactive
line mode to stop processing immediately and return you to your operating
environment.
- n
- is an integer value that enables you to
specify a condition code that SAS returns to the operating environment when
it stops executing.
Operating Environment Information: The range
of values for n depends on your operating environment. ![[cautionend]](../common/images/cautend.gif)
The ABORT statement
causes SAS to stop processing the current DATA step. What happens next depends
on
- the method you use to submit your SAS statements
- the arguments you use with
ABORT
- your operating environment.
The ABORT statement usually appears in a clause of an
IF-THEN statement or a SELECT statement that is designed to stop processing
when an error condition occurs.
Note: When you execute
an ABORT statement in a DATA step, SAS does not use data sets that were created
in the step to replace existing data sets with the same name.
Operating Environment Information: The only difference between the ABEND
and RETURN options is that with ABEND further action is based on how your
operating environment and site treat jobs that end abnormally. RETURN simply
returns a condition code that indicates an error.
- When you use the SAS windowing environment or
interactive line mode, the ABORT statement and the STOP statement both stop
processing. The ABORT statement sets the value of the automatic variable _ERROR_
to 1, and the STOP statement does not.
- In batch or noninteractive mode, the ABORT and
STOP statements also have different effects. Both stop processing, but only
ABORT sets the value of the automatic variable _ERROR_ to 1. Use the STOP
statement, therefore, when you want to stop only the current DATA step and
continue processing with the next step.
This example uses the ABORT statement as part of an
IF-THEN statement to stop execution of SAS when it encounters a data value
that would otherwise cause a division-by-zero condition.
if volume=0 then abort 255;
density=mass/volume;
The n value causes SAS
to return the condition code 255 to the operating environment when the ABORT
statement executes.
