Data Set Options

BLKSIZE= is now available as a system option.

Functions

The following functions are new.

DINFO: returns specified information about a directory in a partitioned data set (PDS), a partitioned data set extended (PDSE), or UNIX System Services.
DOPEN: opens a directory and returns a directory identifier value.
DOPTNAME: returns information about directory attributes.
DOPTNUM: returns the number of information items available for a directory.
FCLOSE: closes an external file that was opened with FOPEN.
FDELETE: deletes data sets.
FEXIST: verifies the existence of an external file associated with a fileref and returns a value.
FILENAME: assigns or deassigns a fileref for an external file.
FILEREF: verifies that a fileref has been assigned and returns a value.
FILEXIST: verifies the existence of an external file based on its physical filename and returns a value.
FINFO: returns the value of a file information item.
FOPEN: opens an external file and returns a file identifier value.
FOPTNAME: returns the name of an item of information for a file.
FOPTNUM: returns the number of available file information items.
LIBNAME: assigns or deassigns a libref for a SAS data library and returns a value.
MOPEN: opens a file by directory ID and member name and returns either the file identifier or 0.
PATHNAME: returns the physical name of a SAS data library or an external file or returns a blank.
SYSGET: returns the values of a specified host-environment variable.

Procedures

For detailed information on the following changes, see Procedures in the OS/390 Environment.

The following procedures are new:

PROC DBF

is now supported in the OS/390 environment. With a license for SAS/ACCESS for PC File Formats, you can use PROC DBF to convert dBASE files to SAS data sets or SAS data sets to dBASE files.

PROC ITEMS

enables you to create, modify, and delete itemstores, which are special file formats used to store information relating to the SAS session.
The following procedures have changed:

PROC CIMPORT

no longer supports background color options.

PROC OPTIONS

In Version 8, supports the following parameters: DEFINE, GROUP=, OPTION=, and VALUE.

PROC TAPELABEL

now produces its output through the Output Delivery System. This procedure also has new DUMP=, BLOCKS, and RECORDS options for specifying dumps to tape.

Statements

FILE

The FILE statement now supports two new options:

LINESIZE=: works with the LRECL= option to specify the maximum number of columns in print files, non-print files, and the SAS log.
PRINT | NOPRINT: specifies whether carriage-control characters are placed in all lines of output that are directed to print files or to the SAS log.

FILENAME

In SAS Version 8, the FILENAME statement supports the EMAIL device type, which allows you to send electronic mail from within SAS.

SYSTASK LIST

lists asynchronous tasks.

WAITFOR

suspends execution of the current SAS session until the specified tasks finish executing.

System Options

The following system options are new:

DLINITDEFER

suppresses synchronization of VTOC entry at library creation time.

DLTRUNCHK

checks for SAS data library truncation.

FILESYSTEM=

specifies the default file system access method that is used when the filename is ambiguous.

MEMLEAVE=

specifies the amount of memory reserved for use by the operating environment.

MSG=

specifies the partitioned data set that contains SAS messages. (This option replaces SASMSG=.)

MSGCASE

specifies uppercase or lowercase message display.

MSGLOAD

enables message files to be closed and reloaded.

MSGSIZE=

specifies the size of the message storage cache.

SORTALTMSGF

enables sorting with alternate message flags.

SORTBLKMODE

enables block-mode sorting.

SORTBUFMOD

enables modification of the sort utility output buffer.

SORTDEVWARN

enables device type warnings.

SORTUADCON

specifies whether the host sort utility supports passing a user address constant to the E15/E35 exits.

SVC11SCREEN

specifies whether to enable SVC 11 screening to obtain host date and time information.

XCMD

enables the use of operating environment commands in a SAS session
The following system options are now obsolete:
- APPCSEC=
- CODEPASS=
- CODEPCT=
- LU0MODE=
- LU0SEC=
- TCPSEC=
The following system options are now documented in SAS Language Reference: Dictionary because they no longer have host-specific aspects:
- CLEANUP
- COMAMID
- MAPS=
- NEWS=
- REMOTE=
- RSASUSER

Windows and Commands

The SAS Explorer windowing environment contains the following host-specific windows, all of which are new since SAS Version 6.09E:

DSINFO

provides information about a cataloged physical file.

FILENAME

displays assigned filerefs and their associated filenames.

FNAME

displays allocated DDnames, their associated data set names, and data set information.

LIBNAME

lists all the libraries that are currently assigned in your SAS session.

MEMLIST

displays a member list for a partitioned data set (PDS) or for a series of partitioned data sets in a concatenation.

New or updated windows of the FORM subsystem include:

IBM 3800 Print-File Parameter Frame: requests IBM 3800 print-file parameters.
TSO Print-File Parameter Frame: requests TSO print-file parameters.

New or updated commands include:

DFLTACTION: simulates a mouse double-click.
DLGENDR: ends the SAS session.
EXPLODE: displays the full length of truncated text entry fields.
INCLUDE: copies the contents of an external file into the current window.
TSO: issues a TSO command or invokes a CLIST or a REXX exec from the command line.
WIDGNEXT: moves the keyboard focus from one widget to the next widget.
WIDGPREV: moves the keyboard focus from one widget to the previous widget.

See Windows and Commands in the OS/390 Environment for information about new commands and the new implementation of the DSINFO, FNAME, and MEMSIZE windows in the SAS Explorer windowing environment.
