Abstract

In the field of mixed 16-bit and 32-bit code, a method and mechanism are provided to implement alterations in the dynamic portion of memory containing the data objects used by code in the 16-bit environment so that such data is accessible to code from the 32-bit environment. The code necessary to implement the method is generated automatically by an enhanced compiler on identifying a 16-bit linkage in the 32-bit code. Once the data objects in the stack are accesible to the 32-bit code, a function in the 16-bit code can successfully call a function in 32-bit code.
