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.
