| What's New |
| Overview |
The SAS 9.2 Base new features, language elements, and enhancements to the language elements continue to expand the capabilities of SAS:
SAS now supports the next generation Internet Protocol, IPv6, as well as IPv4.
The DATA step component Java object enables instantiation of Java classes and accessing fields and methods on resultant objects.
The SAS logging facility is a new logging subsystem that can be used to collect, categorize, and filter log events and write them to various output devices. The logging facility can be used to log SAS server events or events that are initiated from SAS programs. This feature is new for SAS 9.2 Phase 2.
In addition to SAS Monospace and SAS Monospace Bold TrueType fonts, new TrueType fonts are available when you install SAS.
Universal Printing now supports Scalable Vector Graphics (SVG), Portable Network Graphics (PNG), and PDFA-1b print output formats.
You can access remote files by using the Secure File Transfer Protocol (SFTP) access method.
SAS now reads and writes ISO 8601 dates, time, and intervals.
In support of batch programming, if a program terminates without completion, the new checkpoint mode enables programs to be resubmitted in restart mode, resuming with the DATA or PROC step that was executing when the program terminated.
In the "Functions and CALL Routines" section there are several new and enhanced functions as well as functions that were previously in other products and that are now part of Base SAS. The functions that moved from the Risk Dimensions product calculate the call and put prices from European options on futures, based on various models. The functions that moved from SAS/ETS return information about various date and time intervals. The functions from SAS High-Performance Forecasting return specific dates.
The documentation for string functions and CALL routines now has a restriction that identifies whether theses functions and CALL routines support Single Byte Character Sets (SBCS), Double Byte Character Sets (DBCS), or Multi-Byte Character Sets (MBCS). This distinction is important because improper use of these functions and CALL routines can result in unexpected behavior in programs that are written in a non-English language. The description for the restrictions is located in the Function Compatibility with DBCS, MBCS, and SBCS Character Sets section of the documentation.
In a DATA step, you can track the execution of code within a DO group. The DATA statement has an optional argument for you to write a note to the SAS log when the DO statement begins and ends.
New SAS system options enable you to set a default record length, specify options for accessing PDF files, specify values for Scalable Vector Graphics, support the checkpoint mode and the restart mode, and support fonts.
Some of the new features for the DATA step object attributes, operators, and methods remove all items from the hash object without deleting the instance of the hash object, consolidate the FIND and ADD methods into a single method call, return the number of items in the hash object, and specifies a starting key item for iteration.
In previous versions of SAS Language Reference: Dictionary, references to language elements in other publications were included in their respective dictionary for each language element type. For example, you could find a reference for the $BIDI format in the format dictionary entries. You can now find references to language elements that are documented in other publications within each section for the language element types. Online, this section appears just before the dictionary entries for each language element type. In the PDF or print copy, this section appears as the last topic for each language element type.
A section that describes how SAS syntax is written has been added. This section contains examples of how to interpret the syntax.
| SAS System Features |
If a batch program terminates before it completes and it was started in checkpoint mode, the program can be resubmitted in restart mode, resuming with the DATA or PROC step that was executing when the program terminated. DATA and PROC steps that have already completed do not need to be rerun. See "Checkpoint Mode and Restart Mode" in SAS Language Reference: Concepts.
In SAS 9.1.3, the formats and informats that support the ISO 8601 basic and extended time notations were documented in the SAS 9.1.3 XML LIBNAME: User's Guide. These formats and informats have been renamed and are now documented in SAS Language Reference: Dictionary.
The new names clearly distinguish the basic and extended formats and informats. You can see the renamed formats and informats in their respective sections in the topics that follow. In addition, a new CALL routine, IS8601_CONVERT, converts ISO 8601 intervals to datetime and duration values, and datetime and duration values to an ISO 8601 interval.
SAS 9.2 introduces support for the "next generation" of Internet Protocol, IPv6, which is the successor to the current Internet Protocol, IPv4. Rather than replacing IPv4 with IPv6, SAS 9.2 supports both protocols. A primary reason for the new protocol is that the limited supply of 32-bit IPv4 address spaces is being depleted. IPv6 uses a 128-bit address scheme, which provides more IP addresses than IPv4 did.
For more information, see Internet Protocol Version 6 (IPV6) in SAS Language Reference: Concepts.
In SAS 9.2, all Universal Printers and many SAS/GRAPH devices use the FreeType engine to render TrueType fonts for output in all of the operating environments that SAS software supports. In addition, by default, many SAS/GRAPH device drivers and all Universal Printers generate output using ODS styles, and these ODS styles use TrueType fonts.
In addition to SAS Monospace and SAS Monospace Bold, 40 additional fonts (TrueType) are available when you install SAS:
Three Latin fonts compatible with Microsoft
Ten graphic symbol fonts
Eight multilingual Unicode fonts
Nineteen monolingual Asian fonts
In the third maintenance release for SAS 9.2, the MingLiU_HKSCS TruType font is new. In addition, the HeiT, MingLiU, MingLiU_HKSCS, and PMingLiu fonts support the HKSCS2004 (Hong Kong Supplemental Character Set) characters.
New Universal printers include the following:
| PDFA |
produces an archivable PDF compliant with PDF/A-1b . |
| PNG |
produces Portable Network Graphics, which is a raster image format that is designed to replace the older simple GIF and the more complex TIFF format. |
| PNGt |
produces transparent Portable Network Graphics. |
| SVG |
produces Scalable Vector Graphics, which is a language for describing two-dimensional graphics and graphical applications in XML. |
| SVGt |
produces transparent Scalable Vector Graphics. |
| SVGnotip |
produces Scalable Vector Graphics without tooltips. |
| SVGView |
produces Scalable Vector Graphics with controls to navigate through multi-page SVG documents. |
| SVGZ |
produces compressed Scalable Vector Graphics. |
For more information, see Printing with SAS in SAS Language Reference: Concepts.
The SAS logging facility is a flexible, configurable logging subsystem that you can use to collect, categorize, and filter log events and write them to a variety of output devices. The SAS language now includes autocall macros, functions, and DATA step component objects for creating logging facility components that categorize log events. The logging facility and the SAS log are two separate logging systems. For more information, including the reference documentation for the logging facility language elements, see The SAS Logging Facility in SAS Logging: Configuration and Programming Reference. This feature is new for SAS 9.2 Phase 2.
In a WHERE expression, the LIKE operator now supports an escape character. The escape character enables you to search for the percent sign (%) and the underscore (_) characters in values. For more information, see Syntax of WHERE Expression in SAS Language Reference: Concepts.
The DATA step component Java object enables you to instantiate Java classes and access fields and methods on the resultant objects. Although the documentation for the DATA step component Java object for SAS 9.2 Phase 1 has been available on http://support.sas.com, the documentation is available in SAS Help and Documentation for SAS 9.2 Phase 2.
The remote browser has been used in some operating environments in prior releases of SAS to view SAS Help and ODS HTML output. You can now view SAS Help and ODS HTML output, and PDF and RTF output under z/OS, OpenVMS, UNIX, and Windows 64-bit environments. Windows 32-bit environments use the SAS browser to view Help and ODS output.
You enable remote browsing by configuring these system options:
| HELPBROWSER= |
specifies whether you want to use the remote browser or the SAS browser. |
| HELPHOST= |
specifies the name of the computer where the remote browser sends Help and ODS output. |
| HELPPORT= |
specifies the port number for the remote browser client. |
For more information about remote browsing, see the Help documentation for your operating environment: OpenVMS, UNIX, Windows, z/OS

retry lowercase directory or member names from WebDAV servers by using an autocall macro.
a new argument enables you to specify formatting options for the ODS HTML, RTF, and PRINTER(PDF) destinations.
The filename of a file that is located in an aggregate storage location and does not have a valid SAS name can be used as a fileref if the filename is enclosed in quotation marks.
A new option enables you to specify a character string as an alternate delimiter (other than a blank) to be used for LIST input.
A new optional argument specifies the type of device or the access method that is used if the fileref points to an input or output device or location that is not a physical file.
When you assign a libref to a file on a WebDAV server, the path (URL location), user ID, and password are associated with that libref. After the first libref is assigned, the user ID and password will be validated on subsequent attempts to assign another libref to the same library.
SAS will honor a lock request on a file on a WebDAV server only if the file is already locked by another user.
Two new WebDAV options enable you to do the following:

prompt the user for an ID and password.
a new argument enables you to specify at least two existing SAS data sets by using either a numbered range list or a named prefix list.
a new argument creates and names a variable that stores the name of the SAS data set from which the current observation is read. The stored name can be a data set name or a physical name. The physical name is the name by which the operating environment recognizes the file.
a new argument enables you to specify at least two existing SAS data sets by using either a numbered range list or a named prefix list.
added an argument that enables you to specify formatting options for the ODS HTML, RTF, and PRINTER(PDF) destinations.
The following system options are new:
specifies the level of optimization to perform during code optimization. This feature is new for SAS 9.2 Phase 2 and later.
specifies the output model type for the MODEL procedure.

specifies an optional number of extra buffers to be allocated for navigating an index file. SAS automatically allocates a minimal number of buffers in order to navigate the index file. Typically, you do not need to specify extra buffers. However, using IBUFNO= to specify extra buffers could improve execution time by limiting the number of input/output operations that are required for a particular index file.
specifies a SAS data set that contains user-supplied holidays that can be used by the INTNX and INTCK functions. This feature is new for SAS 9.2 Phase 2 and later.
specifies the JPEG quality factor that determines the ratio of image quality to the level of compression for JPEG files processed by the SAS/GRAPH JPEG device driver.

specifies whether the SQL procedure replaces references to the DATE, TIME, DATETIME, and TODAY functions in a query with their equivalent constant values before the query executes.
for the SQL procedure, specifies the engine type that a query uses for which optimization is performed by replacing a PUT function in a query with a logically equivalent expression.
for the SQL procedure when the SQLREDUCEPUT= system option is set to NONE, specifies the minimum number of observations that must be in a table for PROC SQL to consider optimizing the PUT function in a query.
for the SQL procedure when the SQLREDUCEPUT= system option is set to NONE, specifies the minimum number of SAS format values that can exist in a PUT function expression in order for PROC SQL to consider optimizing the PUT function in a query.
specifies whether the SQL procedure can process queries that use remerging of data.
specifies whether the SQL procedure keeps or discards updated data if errors occur while the data is being updated.
specifies whether to run a batch program in checkpoint-restart mode. In checkpoint-restart mode, if a batch program terminates during execution, the program can be restarted beginning with the DATA or PROC step that was executing when the program terminated.
specifies the libref which identifies the library that contains the checkpoint-restart data.
specifies whether to start a batch program using the checkpoint data.
specifies whether to display the paging control buttons and an index in a multi-page SVG document.
specifies the height of the viewport unless the SVG output is embedded in another SVG output; specifies the value of the HEIGHT attribute of the outermost <svg> element in the SVG file.
specifies whether to force uniform scaling of SVG output; sets the preserveAspectRatio attribute on the outermost <svg> element.
specifies the title in the title bar of the SVG output; specifies the value of the <title> element in the SVG file.
specifies the coordinates, width, and height that are used to set the viewBox attribute on the outermost <svg> element, which enables SVG output to scale to the viewport.
specifies the width of the viewport unless the SVG output is embedded in another SVG output; specifies the value of the width attribute of the outermost <svg> element in the SVG file.
specifies the x-axis coordinate of one corner of the rectangular region into which an embedded <svg> element is placed; specifies the x attribute on the outermost <svg> element of the SVG file.
specifies the y-axis coordinate of one corner of the rectangular region into which an embedded <svg> element is placed; specifies the y attribute on the outermost <svg> element of the SVG file.
specifies whether to enable compression of Universal Printer and SAS/GRAPH print files.
specifies the type of message to write to the SAS log if the length of a variable is increased when the input data set is read using the SET, MERGE, UPDATE, or MODIFY statements. This option is new for SAS 9.2 Phase 2.
The following system options have a new argument:
For data sets, automatically repairs the data set without the indexes and integrity constraints, deletes the index file, updates the data file to reflect the disabled indexes and integrity constraints, and limits the data file to be opened only in INPUT mode.
specifies whether analytic derivatives are computed for user-defined functions.
The following system options are enhanced:
SAS writes the autoexec file statements to the SAS log.
You can now specify multiple Simple Mail Transfer Protocol (SMTP) mail servers.
In the third maintenance release for SAS 9.2, you can use encoded e-mail passwords. These passwords are encoded with PROC PWENCODE.
All e-mail system options can now be set at any time. They are no longer restricted to being set when SAS starts.
The default value for the OVP system option is now NOOVP.
You can specify the name of a Universal Printer to which the SYSPRINTFONT system option setting applies.
The syntax for the following system options is different when these system options are used after SAS starts, as compared to the syntax that is used when SAS starts. For the syntax to use when SAS starts, see the documentation for your operating environment. This feature is new for SAS 9.2 Phase 2:
Appends a value to the existing value of the specified system option.
Inserts the specified value as the first value of the specified system option.
The following system options are no longer supported and have been removed from the documentation:
no longer has an impact on the settings for the LINESIZE, OVP, PAGESIZE, and SOURCE system options when SAS executes.
SAS 9.2 no longer supplies U.S. Census Tract maps for SAS/GIS.
The following system option has been deleted from SAS:
For SAS 9.2 Phase 2 and later, the Java object language elements in Java Object Language Elements are now documented in SAS Language Reference: Dictionary.
The following hash and hash iterator methods are new:
removes all items from the hash object without deleting the hash object instance.
determines whether two hash objects are equal.
sets the current list item to the next item in the current key's multiple item list and sets the data for the corresponding data variables.
sets the current list item to the previous item in the current key's multiple item list and sets the data for the corresponding data variables.
determines whether there is a next item in the current key's multiple data item list.
determines whether there is a previous item in the current key's multiple data item list.
consolidates the FIND and ADD methods into a single method call.
removes the data that is associated with the specified key's current data item from the hash object.
replaces the data that is associated with the current key's current data item with new data.
specifies a starting key item for iteration.
retrieves the summary value for a given key from the hash table and stores the value in a DATA step variable.
retrieves the summary value for the current data item of the current key and stores the value in a DATA step variable.
The following hash object method is enhanced:
added an optional argument that enables recovery from memory failure when loading a data set into a hash object.
The following hash object attribute is new:
returns the number of items in the hash object.
The _NEW_ statement has been reclassified as an operator.
For SAS 9.2 Phase 2 and later, the items in a multiple data item list are now maintained in the order in which you insert them.
