Description
Bottom rule

Performance and hardware improvements

  • ARCH(8)/TUNE(8) support
  • PFPO instruction exploitation (to inline conversions between hex, binary and decimal float)
  • HGPR option to allow more exploitation of 64-bit registers in 32-bit code
  • GOFF object support
  • DFP math built-in functions support
  • Exploit the MVCLE hardware instruction in code generated for the LEFT built-in function
  • Exploit the SRSTU hardware instruction in code generated for the INDEX built-in function when applied to the WIDECHAR
  • CMPAT(V3) and other support of 8-byte array bounds, structure sizes etc for stage 1 of 64-bit support

User requirements

Support for the XML System Services parser The new PLISAXC built-in subroutine uses the XML System Services parser. This will provide for namespaces and for parsing XML documents larger than 2 GB

Improved support for UTF-8 and UTF-16

The following new built-in functions will provide better support for UTF-8 and UTF-16:

  • ULENGTH -- Returns the number of UTF-8 or UTF-16 characters in a CHAR or WIDECHAR string, respectively.
  • ULENGTH8 -- Returns the CHAR length if the UTF-16 characters in a WIDECHAR string were converted to UTF-8.
  • ULENGTH16 -- Returns the WIDECHAR length if the UTF-8 characters in a CHAR string were converted to UTF-16.
  • UPOS -- Returns the position of the nth UTF-8 or UTF-16 character in a CHAR or WIDECHAR string, respectively.
  • USUBSTR -- Returns the substring starting with the i'th UTF-8 or UTF-16 character and of length j such characters in a CHAR or WIDECHAR string respectively.
  • UVAlID -- Tests if a CHAR or WIDECHAR string contains valid UTF-8 or UTF-16 data, respectively.
  • UWIDTH -- Returns the width of the nth UTF-8 or UTF-16 character in a CHAR or WIDECHAR string, respectively.

SQL improvements

  • DIMACROSS attribute -- The DIMACROSS option specifies a DIMENSION attribute on a structure but which be removed from the structure and propagated to its children. This attribute is particularly useful with SQL multi-row fetch.
  • DDSQL option -- The DDSQL option allows the user to specify a DDNAME that will be used instead of SYSLIB as the DDNAME to searched for files named in SQL INCLUDE statements. This eases the move from the SQL precompiler to the SQL preprocessor.
  • INCONLY support in the SQL preprocessor -- The SQL preprocessor will now support an INCONLY option. This option acts similar to the SQLONLY option in the MACRO preprocessor: under PP(SSQL('INCONLY')) only EXEC SQL INCLUDE statements will be processed and all other EXEC SQL statements will be left as is.
  • LISTVIEW option -- The SOURCE, AFTERMACRO, etc suboptions of the TEST option must now be specified as suboptions of the new LISTVIEW option. This will permit these suboptions to be used without incurring any of the overhead of the TEST option. LISTVIEW(AFTERSQL) is useful with some SQL tools.
  • DBCS -- DBCS is now supported by the integrated SQL preprocessor (as it had already been supported by the MACRO and CICS preprocessors).

Additional user control of built-in function behavior

  • USAGE(HEX) option -- The USAGE option -- Now accepts HEX as a suboption.
  • USAGE(SUBSTR) option -- The USAGE option now accepts SUBSTR as a suboption.
  • FOFLONMULT suboption to DECIMAL -- The DECIMAL option will be expanded to have a new suboption: (NO)FOFLONMULT.

New and improved built-in functions

  • ONLINE built-in function -- The ONLINE built-in function returns a FIXED BIN(31) value which is the user source line number where a condition was raised.
  • REG12 built-in function -- This built-in function returns the current value of register 12.
  • FLOATDEC, FLOATBIN, FIXEDDEC, FIXEDBIN built-ins -- These built-in functions are useful in specifying with one built-in function the attributes desired for a numerical result. They can be particularly useful in avoiding the 2 conversions that might result if, for example, the DECIMAL and then the FLOAT built-in function were used to convert a FIXED BIN to FLOAT DEC; They are also particularly useful with decimal float point (DFP).
  • REPATTERN improvements -- These 3 additional DB2 date-time formats will be supported:
  • YY-MM-DD
  • MM/DD/YY
  • DD.MM.YY

Miscellaneous other requirements

  • Remove calls to null procedures -- Some programming practices cause the production version of the code to contain calls to procedures consisting of only a PROCEDURE and an END statement (although their test version may have debugging or logging code, for example). The compiler will now detect if any internal procedures are null and then eliminate any calls to them.
  • Support INCDIR under batch -- This function allows hfs files to be included in batch compilations.
  • Support NOINIT on substructures -- The NOINIT attribute will now be allowed on substructures
  • Widen listing header to all of listing -- Instead of truncating the listing header to 25 bytes, the compiler will now place the first 43 bytes from line one in the header line of all pages after page one.
  • Allowance tor trailing OPTIONAL arguments to be omitted in calls to internal procedures -- The omission of trailing OPTIONAL arguments will now be permitted also for internal procedures.
  • NULLSTRADDR suboption to DEFAULT -- The DEFAULT option will be expanded to have a new suboption: (NO)NULLSTRADDR.

New and changed messages

  • Subdivide message IBM2610 -- Message IBM2610 flags built-in references where one argument is FIXED DEC and the other is FIXED BIN or FLOAT.
  • Suppress uninitialized warnings -- The new SUPPRESS attribute will allow a suboption of UNINIT and/or UNREF to be specified. When specified, these will cause the compiler to suppress any messages saying the associated variables are uninitialized or unreferenced, respectively.
  • NOLAXENTRY suboption to the RULES option -- The RULES option will be expanded to have a new suboption: (NO)LAXENTRY.
  • Operations producing FIXED(p,q) with q > p -- The compiler will now flag with a warning message code where the result of a FIXED operation has a scale factor greater than its precision (for example when multiplying two FIXED DEC(15,8) values).
  • LINESIZE - RECSIZE mismatches -- The compiler will now flag with an error message code where an OPEN specifies a LINESIZE that is too large for the LRECL etc specified in the file's declare.
  • POINTER / FIXED BIN overlays -- The compiler will now flag with a warning message code where a POINTER or an OFFSET is declared as BASED on the ADDR of a FIXED BIN (or vice versa). This will help identify code that will need to be changed before moving to 64-bit.
  • OR, NOT or QUOTE with no valid characters -- The compiler will now recognize and flag this error with a severe message.
  • INITIAL with PARAMETER -- The compiler will now flag this error with a unique error message.
  • INITIAL with DEFINED -- The compiler will now flag this error with a unique error message.
  • Allocations where an aggregate is mapped via a library call -- The compiler will now flag such code with an informational message.
Debug Tool for z/OS V9.1

The previous releases of Enterprise PL/I were available with Alternate Function or Full Function offerings. The Alternate Function offering included the PL/I compiler. The Full Function offering included both the PL/I compiler and the debug capability found in Debug Tool for z/OS. Enterprise PL/I Version 3.8 provides the PL/I compiler only. It is not available with a Full Function offering. The latest version of that debug capability can be obtained in Debug Tool for z/OS V9.1, which can be ordered separately. For more information on Debug Tool for z/OS V9.1, refer to Software Announcement 208-264, dated September 23, 2008.
