Hi, I'm running R v1.9.0 on WinXP Pro. I noticed that R.exe and Rterm.exe behave differently on Ctrl-C. Starting a Windows Command prompt (cmd.exe) you get from running Rterm.exe:
C:\Program Files\R>rw1090\bin\Rterm.exe --vanilla --quiet > ^C > ^C > 1+1 [1] 2 > Sys.sleep(100) # Ctrl-C after a few seconds > ^C > ^C > 1+1 [1] 2 > q() C:\Program Files\R> C:\Program Files\R> Ctrl-C works as expected. Exiting R and you're back at a "clean" prompt. Now, try the same thing with R.exe (from a restarted prompt): C:\Program Files\R>rw1090\bin\R.exe --vanilla --quiet > ^C > ^C > 1+1 [1] 2 > Sys.sleep(100) ^C C:\Program Files\R> > Strange things happen. R seems still to be running but has at the same time returned(?) the control back to the Command prompt. Try to continue by pressing ENTER and/or type 1 + ENTER, 2 + ENTER etc and you'll see that eventually you get replied from R also: > 1+1 '1+1' is not recognized as an internal or external command, operable program or batch file. C:\Program Files\R>1+1 '+1' is not recognized as an internal or external command, operable program or batch file. C:\Program Files\R>q C:\Program Files\R> function (save = "default", status = 0, runLast = TRUE) .Internal(quit(save, status, runLast)) <environment: namespace:base> > Clearly both cmd.exe and R is trying to parse the stdin. Some keystrokes goes to R and some to cmd.exe.
