Write the PUSH and POP routines discussed in Example 4.3 using assembly language

To understand Parnas partitioning, consider writing a module to implement an abstract data type called a stack with associated operations PUSH and POP. The implementation of this module should be hidden from all calling modules. A data item should be passed to the PUSH procedure with assurance that it will be placed on the stack. Similarly, the POP procedure should return a data item from the stack and adjust the stack accordingly. Access to the stack in memory via any means other than PUSH and POP (except perhaps for initialization) should be prohibited.
