Instructs the assembler to load and use the DOS operation code
table. The DOS operation code is designed specifically 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-4).
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).
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).
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).
Notes:
These operation code tables do not contain symbolic operation codes
for machine instructions that are unique to IBM 4300 Processors
operating in ECPS:VSE mode.
