Language Environment enhancements for OS/390 & VM V2R5


Language Environment did not have an explicit release for V2R5, but enhancements were made with APARs. Some of the enhancements are:

  • Sub-option, NOSPIE, added to TRAP run-time option. (Available with APAR PQ06268.)

    NOSPIE specifies that Language Environment will not issue the ESPIE macro. When you specify NOSPIE with the TRAP(ON) suboption, Language Environment will handle program interrupts and abends through an ESTAE. The NOSPIE suboption is ignored when it is specified with TRAP(OFF).

    You should use TRAP(ON,NOSPIE) if you do not want Language Environment's Condition Manager to issue an ESPIE because your application has issued an ESTAE to get control first for abends and program interrupts.

  • Below the Line Storage Reduction

    The amount of storage used below the 16 megabyte line has been reduced for C Runtime Library processing. This enables more concurrent threads to exist in the address space.
    Access to this function is available through PTF UQ11563.

  • Enhanced National Language Support (NLS) in Language Environment

    Language Environment augments its extensive collection of code page conversion services with new converters for China and Japan. These support:


    • The Guo Biao Kuo (GBK) extension to the Simplified Chinese code set that is used in the PRC.

      The GBK extension expands the Guo Biao (GB) code set to include all other Han characters that are defined in the ISO 10646-1 Unicode ideographic character set. This provides a basis for writing multilingual applications in the PRC, encompassing both Simplified Chinese and traditional Chinese.
      Access to this function is available through PTF UQ09126.

    • ISO-2022-JP encoding of Japanese characters

      This capability is a significant NLS improvement because it is needed in almost all Japanese mail traffic on the Internet and in about a third of all Japanese Web data.
      Access to this function is available through PTF UQ08178.
