Description

High Level Assembler for z/OS, z/VM, and z/VSE V1.6 extends the capabilities of previous releases of High Level Assembler. Among the enhancements are:

  • An internal HLASM Services Interface allows user exits to allocate and free storage, to write operator messages, and to access date and time information, enabling you to write exits without operating system-dependent instructions.
  • To eliminate possible conflicts between identically-named macros and machine instructions, High Level Assembler supports suffix tags for operation mnemonics. If you need to use a macro and a machine instruction named XXX in the same source program, you may add tags to the mnemonic to indicate the desired resolution, as in this example:

         XXX       A,B,C  Invokes either the macro or machine
                           instruction, whichever is most recently
                           defined
         XXX: MAC  A,B,C  Always invokes macro XXX
         XXX: ASM  A,B,C  Always invokes assembler instruction XXX

  • To enable wider use of long-displacement instructions, High Level Assembler adds the QY-type and SY-type address constants, which resolve their operands to signed 20-bit displacements.
  • The ambiguous result of using an Opcode attribute reference (O') in non-conditional assembly statements is avoided by limiting such references to conditional assembly statements.
  • Among items introduced in the service stream for Release 5 are
    • Support for external declaration of PART symbols
    • Support for z9-109 instructions and the new ZS3 sub-option for the OPTABLE option
    • Support for z10 instructions and the new ZS4 sub-option for the OPTABLE option
    • Support for z9 decimal floating-point and other instructions
    • Support for three decimal floating-point data types
    • Improvements to the FLAG(PAGE0) option, to better diagnose unintended references to low storage
    • Ability to add the OPTABLE operand to the ACONTROL statement to allow localized control over mnemonic resolution
    • Support for unsigned fixed-point binary constants
    • Insignificant leading zeros may be specified on decimal, binary, and hexadecimal self-defining terms
    • Clarification of symbol-table information for qualifier symbols
    • Support for new z9 instructions
    • Integrated support for all System z instructions, including those for the z10 series of processors
    • New diagnostics that help programmers create more reliable programs
  • The High Level Assembler for Linux on System z Feature supports assembling on IBM Linux for System z. Source, macro, and COPY files can be in single-byte ASCII or EBCDIC, and traditional or Linux ELF object files can be generated.
