AMODE Instruction
name
is the name field that associates the residence mode with a control
section. If there is a symbol in the name field, it must also appear in the
name field of a START, CSECT, RSECT, or COM instruction in this
assembly. If the name field is space-filled, there must be an unnamed
control section in this assembly. If the name field contains a sequence
symbol (see “Symbols” on page 29 for details), it is treated as a blank
name field.
If the extended object format is being generated (GOFF
assembler option), name is a relocatable symbol that names an entry point
specified on an ENTRY instruction.
24 Specifies that 24-bit addressing mode is to be associated with a control
section, or entry point.
31 Specifies that 31-bit addressing mode is to be associated with a control
section, or entry point.
64 Specifies that 64-bit addressing mode is to be associated with a control
section, or entry point (see “64-bit Addressing Mode” on page 101).
ANY
ANY31
The same as ANY31.
The control section or entry point is not sensitive to whether it is entered in
AMODE 24 or AMODE 31.
| ANY64 The control section or entry point is not sensitive to whether it is entered in
| AMODE 24, AMODE 31, or AMODE 64.
Any field of this instruction may be generated by a macro, or by substitution in open
code.
If symbol denotes an ordinary symbol, the ordinary symbol associates the
addressing mode with a control section. The ordinary symbol must also appear in
the name field of a START, CSECT, RSECT, or COM instruction in this assembly.
If symbol is not specified, or if name is a sequence symbol, there must be an
unnamed control section in this assembly.
Notes:
1. AMODE can be specified anywhere in the assembly. It does not initiate an
unnamed control section.
| 2. AMODE is permitted on external labels (EXTRNs) and Entry labels for both
| GOFF and OBJ formats and Parts for GOFF formats.
3. An assembly can have multiple AMODE instructions; however, two AMODE
instructions cannot have the same name field.
4. The valid and invalid combinations of AMODE and RMODE are shown in the
following table. Note that combinations involving AMODE 64 and RMODE 64
are subject to the support outlined in “64-bit Addressing Mode” on page 101.
