Windows 3.1 is preferred, but WGNUPLOT will run under Windows 3.0 with the following restrictions:
1. COMMDLG.DLL and SHELL.DLL (available with Windows 3.1 or Borland C++ 3.1) must be in the windows directory.
2. WGNUPLOT.HLP produced by Borland C++ 3.1 is in Windows 3.1 format. You need to use the WINHELP.EXE supplied with Borland C++ 3.1.
3. It won't run in real mode due to lack of memory.
4. Truetype fonts are not available in the graph window.
5. Drag-drop does not work.
