Addressing mode (AMODE) and residence mode (RMODE)
Use the AMODE instruction to specify the addressing mode to be associated with the control sections in the object program.
The addressing modes are:
- 24
- 24-bit addressing mode
- 31
- 31-bit addressing mode
- 64
- 64-bit addressing mode - See note below
- ANY
- The same as ANY31
- ANY31
- 24-bit or 31-bit addressing mode
- ANY64
- 24-bit, 31-bit, or 64-bit addressing mode
Use the RMODE instruction to specify the residence mode to be associated with the control
sections in the object program. The residence modes are:
- 24
- Residence mode of 24. The control section must reside below the 16MB line.
- 31
- Residence mode of either 24 or 31. The control section can reside above or below the 16MB line.
- 64
- Residence mode of 64 - See note below.
- ANY
- Is understood to mean RMODE(31).
You can specify the AMODE and RMODE instructions anywhere in the assembly source. If the name field in either instruction is left blank, you must have an unnamed control section in the assembly. These instructions do not initiate an unnamed control section.
Note: The 64-bit addressing and residence modes are accepted
and processed by the assembler. However, other operating system components
and utility programs may not be able to accept and process information
related to these operands.
