VNFERR

Valid in:	configuration file, SAS invocation, OPTIONS statement, Systems Options window
Category:	Environment Control: ERRORHANDLING

Syntax Description

VNFERR

specifies that SAS either issue a warning and error message, or set _ERROR_=1 and stop processing, or both if the error is severe enough to interrupt processing.

NOVNFERR

specifies that SAS issue a warning for a variable that is not found, but not set _ERROR_=1 or stop processing.

Details

The VNFERR system option specifies whether SAS sets the error flag (_ERROR_=1) for a missing variable when a _NULL_ data set (or a data set that is bypassed by the operating environment control language) is used in a MERGE statement within a DATA step.

Comparisons

• VNFERR is similar to the BYERR system option, which issues an error message and stops processing if the SORT procedure attempts to sort a _NULL_ data set.

• VNFERR is similar to the DSNFERR system option, which generates an error message when a SAS data set is not found.

System Options: BYERR DSNFERR
