Default

OPTABLE(UNI,NOLIST)

Abbreviation

OP

Restrictions

None

DOS

Instructs the assembler to load and use the DOS operation code table. The DOS operation code is designed for assembling programs previously assembled using the DOS/VSE assembler. The operation code table contains the System/370 machine instructions, excluding those with a vector facility.

ESA

Instructs the assembler to load and use the operation code table that contains the ESA/370 and ESA/390 architecture machine instructions, including those with a vector facility. Equivalent to MACHINE(S390E).

UNI

Instructs the assembler to load and use the operation code table that contains the System/370 and System/390 architecture machine instructions, including those with a vector facility, and Z/Architecture machine instructions.

XA

Instructs the assembler to load and use the operation code table that contains the System/370 extended architecture machine instructions, including those with a vector facility. Equivalent to MACHINE(S370XA).

370

Instructs the assembler to load and use the operation code table that contains the System/370 machine instructions, including those with a vector facility. Equivalent to MACHINE(S370).

YOP

Same as OPTABLE(ZOP) but with the addition of the long displacement facility. Equivalent to MACHINE(ZSERIES-2).

ZOP

Instructs the assembler to load and use the operation code table that contains the symbolic operation codes for the machine instructions specific to z/Architecture systems. Equivalent to MACHINE(ZSERIES).

ZS3

Instructs the assembler to load and use the operation code table that contains the symbolic operation codes for the machine instructions specific to z/Architecture systems. Equivalent to MACHINE(ZSERIES-3).

ZS4

Instructs the assembler to load and use the operation code table that contains the symbolic operation codes for the machine instructions specific to z/Architecture systems. Equivalent to MACHINE(ZSERIES-4).

ZS5

Instructs the assembler to load and use the operation code table that contains the symbolic operation codes for the machine instructions specific to z/Architecture systems. Equivalent to MACHINE(ZSERIES-5).

ZS6

Instructs the assembler to load and use the operation code table that contains the symbolic operation codes for the machine instructions specific to z/Architecture systems. Equivalent to MACHINE(ZSERIES-6).

LIST

Instructs the assembler to produce the Operation Code Table Contents section in the listing. Equivalent to MACHINE(LIST).

NOLIST

Instructs the assembler not to produce the Operation Code Table Contents section in the listing. Equivalent to MACHINE(NOLIST).
