Well, I've spent the day compiling sample programs found in the Index of /HOWTO/NCURSES-Programming-HOWTO.
Some compile and run fine, some I needed to correct for them to run, and others either hang, or bomb due to access violations.
However, I have discovered that the Menu and Form functionality is not implemented in PDCurses - apart from the basic curses functionality only the Panels functions are implemented. This rather limits the use of PDCurses as a windowing/menu based/form data entry library. A bit disappointing really.
