PSPP currently runs only as a console-mode application under Windows environments. Since Windows 3.1 does not provide a console, PSPP needs special assistance to run under Windows 3.1. con32s is a small library that I have developed to do this. This directory contains the compiler-independent portion of con32s. There is also a small compiler-dependent portion that need to be written for each compiler. See the example for Borland C++ for more details. -blp
