This release provides the following functional enhancements
described in this and the other IBM PL/I books.
Performance improvements
- The ARCH(8) and TUNE(8) options provide exploitation of the z/HE instructions.
- The HGPR option supports using 64-bit registers in 32-bit code.
- The GOFF option supports generation of GOFF objects.
- The PFPO instruction will be exploited in conversions between differing float formats.
- SRSTU will be used in code generated for UTF-16 INDEX.
- Calls to null internal procedures will now be completely removed.
Usability enhancements
- PLISAXC provides for access to the XML System Services parser via a SAX interface.
- The INCDIR option is supported under batch.
- The LISTVIEW option now provides the support previously provided by the AFTERMACRO etc suboptions of TEST.
- The NOLAXENTRY suboption of the RULES option allows for the flagging of unprototyped ENTRYs.
- The (NO)FOFLONMULT suboption of the DECIMAL option allows for control of whether FOFL is raised in MULTIPLY of FIXED DECIMAL.
- The HEX and SUBSTR suboptions of the USAGE option provide more user control of the behavior of the
corresponding built-in functions.
- The DDSQL compiler option provides the ability to specify an alternate DD name to be used for EXEC SQL INCLUDEs.
- The INCONLY suboption provided by the MACRO and SQL preprocessors can request those preprocessors to perform only INCLUDEs.
- The integrated SQL preprocessor will now generate DB2 precompiler style
declares for all *LOB_FILE, *LOCATOR, ROWID, BINARY and VARBINARY SQL types,
in addition to the BLOB, CLOB and DBCLOB SQL types already supported,
when the LOB(DB2) SQL preprocessor option is selected.
