RMODE Instruction
RMODE Instruction
The RMODE instruction specifies the residence mode to be associated with control
sections in the object deck.

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.
24 specifies that a residence mode of 24 is to be associated with the control
section; that is, the control section must be resident below 16 megabytes.
31 specifies that a residence mode of either 24 or 31 is to be associated with the
control section; that is, the control section can be resident above or below 16
megabytes.
64 Specifies that a residence mode of 64 is to be associated with the control
section (see “64-bit Addressing Mode” on page 101).
ANY
is understood to mean RMODE 31.
Any field of this instruction may be generated by a macro, or by substitution in open
code.
Notes:
1. RMODE can be specified anywhere in the assembly. It does not initiate an
unnamed control section.
2. An assembly can have multiple RMODE instructions; however, two RMODE
instructions cannot have the same name field.
3. 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.
