New programs above 16 megabytes

When you write new programs that reside above 16 megabytes, your main concerns are:
  • Dealing with programs that require entry in 24-bit addressing mode or that require parameters to be below 16 megabytes. Note that these are concerns of any 31-bit addressing mode program no matter where it resides.
  • How routines that remain below 16 megabytes invoke the new program.
