Console redirection crashes Hello World

hi,
I just bought pb as it seems to have good console capability, but just hit a problem I hoping there is a solution to.....
Nice simple classic prog:

Code: Select all

OpenConsole()
  PrintN("Hello World")
CloseConsole()

compile as console app, all cpu and tried with/without NT compliance as Helloworld.exe
Run the program from the command line and we get the expected 'Hello World'. problem starts when I try to use console redirection. Run the command

Code: Select all

helloworld >c:\daft

and I expected to get the file c:\daft containing 'Hello World', instead XP Pro shuts down the executable. Has anyone else had this problem? have I missed something in my code? Is there a workaround?

Better mention, doing all this on AMD 1700+ & Windows XP Professional

Hi !
Windows immediately closes the console ...

try:

Code: Select all

OpenConsole() 
  PrintN("Hello World") 
  delay(1000)
CloseConsole()

hi,

thanks for that, doesn't work though. I'm calling the app from an existing console so its not closing. tried setting the delay quite large (100000) still got the same problem. I put the delay before printn() and the program took longer to crash. tried adding inkey() before printn and it waits for a key before crashing, So I think its specifically PrintN() thats causing the crash. Any other ideas?

I will investigate all the console stuff soon, as it seems to be a bit strange.

Thanks, I will watch for any updates.
I'm porting a suite of BCX,QBasic and PowerBasic Dos/Console Apps, so far only the redirection being a major problem.
