Are there any source code examples of how to use 'curses' in C on the RS/6000 with the 'pcc' compiler that I can ftp? Our documentation consists of two pages listing the functions, and suggesting a book by Ken Arnold (which our library does not have). All I want to do is clear the screen, move to a specific row, column location, prompt for input, grab input, and that's it. Any help would be appreciated. jham@cs.umr.edu

I'm having a problem with switch(c) while programming with curses. The keys
don't function as I thought they should. I am by no means an expert C
programmer, and I have only recently been introduced to curses, but I don't see
any syntax problems and the switch statements are pretty straight foward. I am
also not sure if I should use the raw() mode to do this kind of key
manipulation during the switch. Below is basically the switch code that I'm
using. The loop basically checks to see if the key being pressed is a special
key and if it is, it performs some special action.
NOTE: I'm running this on an HP9000/375 HP-UX 7.0 system. I only point this out
because of some of the unique unsupported features of this compiler.
Any help or suggestions would be greatly appreciated. Please send E-mail to
burroak@convex.cl.msu.edu.
Thanks, Jeff

BTW did you remember to call cbreak() and keypad( window, TRUE ) near the beginning? Nick Jacobs

I try this in a VAX-6310 running Ultrix 3.0 and I get an strange result. First of all I need to add the keypad(stdscr,TRUE) option, and when I compile the program with the 'cc' compiler, it doesn't return the correct KEY_* number, but if I compile the same program with the 'vcc' (Vax CC) compiler it works fine. Somebody could explain this? -- Juan Gabriel Ruiz Pinto Internet: Ing. Sistemas Electronicos jgabriel@mtecv2.mty.itesm.mx I.T.E.S.M. Campus Monterrey
