436 FILEMSGS System Option Chapter 18
FILEMSGS System Option
Controls whether you receive expanded dynamic allocation error messages when you are
assigning a physical file
Default NOFILEMSGS
Valid in: configuration file, SAS invocation, OPTIONS statement, OPTIONS window
Category: File Control: EXTFILES, File Control: SASFILES
PROC OPTIONS GROUP= EXTFILES and SASFILES
z/OS specifics: all
Syntax
FILEMSGS | NOFILEMSGS
Details
The FILEMSGS option applies to physical files that are referenced in either a
FILENAME statement or function or in a LIBNAME statement or function.
If FILEMSGS is in effect and you try to assign a data set that is allocated to another
user, SAS generates detailed error messages explaining why the allocation failed.
Under TSO, the messages are written to the display. The display is cleared and the
messages appear. You must press ENTER to return to your session in the windowing
environment. In batch mode, the messages are written to the job log.
If NOFILEMSGS is in effect, you will still receive some error messages in your SAS
log, but they may not be as detailed.
FILENULL System Option
Specifies whether zero-length records are written to external files
Default: FILENULL
Valid in: configuration file, SAS invocation, OPTIONS statement, OPTIONS window
Category: File Control: EXTFILES
PROC OPTIONS GROUP= EXTFILES
z/OS specifics: all
Syntax
FILENULL | NOFILENULL
FILENULL
allows zero-length records to be written to external files. This is the default value.
