doelz@urz.unibas.ch (04/13/91)
I want to show a menu on the screen which is similar to the one you get from
SMG$. The curses package available on VAX C gives the problem that the
cursor key is read as terminator instead of a cursor key. On ultrix, I
cannot even compile it poroperly (it does not matter whether I use curses.h
or cursesX.h). On another Unix box, I can compile it and it looks shown below.
The cursor key is readily interpreted as <ESC>[A as it should.
I would be grateful if someone in netland could explain me what goes wrong on
the VMS side or even get me a piece of code which builds a menu and selects an
item.
Regards
Reinhard
