HOBSET: Set high order bit option

The HOBSET option allows you to specify if the high order bit in each four byte V-type address constant is set according to the AMODE of the target symbol.

HOBSET={NO | YES}

YES: Specifies the high order bit in each V-type address constant is set according to the AMODE of the target entry point. For AMODE(31) or AMODE(ANY) targets, the high order bit is set on (B'1'). If the target is marked AMODE(64), the address constant will not be altered. For AMODE(24), the high order bit is set off.
Note: This operation is completely reversible. On rebinding, V-cons from included program objects revert to their original state, unless HOBSET is specified again.
NO: Specifies the high order bit in each V-type address constant is not to be set according to the AMODE of the target entry point.
NO is the default. The bit is set to off if HOBSET is not specified from any source.

Note: A module or element loaded below 16 MB might need to operate with AMODE(31) if it receives control from another module or element loaded above 16 MB. This allows it to access the caller's data areas.
