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 32-bit environment so that such data is accessible to code from the 16-bit environment. Once the data objects in the stack are accesible to the 16-bit code, a function in the 32-bit code can successfully call a function in 16-bit code.
