Abstract
Global variables are shared between programs associated with different addressing modes. A first program of an application records an allocated address to a global variable in a global variable sharing area (GVSA). The first program is associated with a first addressing mode. The first program specifies the global variable to be shared across different addressing modes. An address of the GVSA is passed to a second program of the application that is loaded after the first program has been loaded. The second program is associated with a second addressing mode different from the first addressing mode. The second program also specifies the global variable in the second program to be shared across different addressing modes. The second program retrieves the allocated address to the global variable from the GVSA based on the address of the GVSA. The second program accesses the global variable based on the retrieved allocated address.
