There are other SCL functions that enable you to determine
the names and values of attributes that your operating system maintains for
external files. These functions are listed in the following sections and
are described completely in the appropriate entry in SAS Component Language Dictionary.
Files and directories have several operating system attributes
that are assigned and maintained by the file management system (for example,
the date modified and name attributes). These attributes can vary among operating
systems and are described in the SAS documentation for your operating environment.
You can use the following SCL functions to determine the attributes and attribute
values for external files:
FOPTNUM |
reports the number of attributes maintained for files
in your operating system. |
FOPTNAME |
returns the name of a file attribute. |
FINFO |
returns the value of a file attribute. |
You can also use SCL functions to find a file's record length
and the position of the column pointer in the FDB.
FRLEN |
returns the length of a record in the FDB. |
FCOL |
returns the position of the column pointer in the FDB. |
You can use SCL functions to rename or delete an external file.
DELETEFDELETE |
delete an external file. |
RENAME |
renames an external file. |
