Addressing mode definitions

The AMODE attribute, located in the PDS directory entry for the module, specifies the addressing mode that the module expects at entry. Bit 32 of the program status word (PSW) indicates the addressing mode of the program that is executing. The system supports programs that execute in either 24-bit or 31-bit addressing mode. The AMODE attribute can have one of the following values:

24

specifies that the program is to receive control in 24-bit addressing mode.

31

specifies that the program is to receive control in 31-bit addressing mode.

ANY

specifies that the program is to receive control in either 24-bit or 31-bit addressing mode.
