E.7.1 WPOINT: A Structure for Bridging Back to 16-
Bit Systems
The Target utility originally was designed to run on 16-bit Windows systems.
With the emergence of 32-bit systems, Target was upgraded to run on these
newer systems. At the same time, Target has maintained its backward
compatibility with the 16-bit systems by including a programming structure
identified to Target as
wpoint (Table E-6).
