Syntax

-SHORTFILEEXT

no argument
specifies that SAS is to define all SAS libraries as three-character file extension libraries.

Details

The -SHORTFILEEXT system option is recommended only for operating systems using a FAT or 8.3 file system where a file name can be no longer than eight characters and a file extension can be no longer than three characters. By default, SAS expects libraries to use long file extensions. When you specify -SHORTFILEEXT, SAS bypasses checking directories for long file extensions. Using -SHORTFILEEXT when using an 8.3 file system improves SAS performance.

Note:   If SAS is installed on an operating system that supports long file extensions, the -SHORTFILEEXT system option cannot be specified on the command line. If this is attempted, SAS will not start.  [cautionend]
