  16. #From swanger@accs.duc.auburn.edu (David Swanger)
  17.  
  18. #I am writing a C program for my SUN IPC Workstation, SunOs 4.1.2,
  19. #and would like to be able to shell in and out of the program.  My
  20. #program uses curses (Sys V).  I tried the following command:
  21.  
  22. #system("/bin/csh");
  23.  
  24. #When the program reached this point, it seemed to shell out (I saw
  25. #the prompt), but the terminal froze up.  Obviously I am missing
  26. #something with either C or curses or system() or something.  I
  27. #would really appreciate some help with this.
  28.  
  29. Ok, ok, I broke down and reread the curses man pages and I discovered
  30. that the following seems to work:
  31.  
  32.   endwin();
  33.   system("/bin/csh");
  34.   doupdate();
  35.  
  36. Thanks to all of the people who sent help with this.
