Hello,

basically what I'm trying to do is to debug a console program that
would be started on the command line with its output redirected, i.e:

TheProgram.exe > PutOutputHere

how do I tell the debugger to redirect the debuggee's output (stdout)
to the file "PutOutputHere" ?

Thank you for your help.

Not related to debugging, but Menu -> Run -> Run Parameters -> Command
line (without appname) "> out.txt" works for me.

Thank you.  I tried that but, it didn't work for me.   My program sees
the ">" and "out.txt" as command line parameters.  It was worth a try.

Are you using a flavor of unix or Windows ?

Not tested: (unix /Mac only)

Tools > Opiton > Debugger: Look through the property grid, there
should be an option about "...Pty...". Try to put your filename there.

This option is global. Not per project

Thank you Martin.  Maybe I didn't set the right field but, I didn't
get any of those I tried to work.  I just added a little bit of code
that is conditionally compiled to do the redirection "manually".  Not
exactly elegant but, it serves the purpose.  It will do and it's
easily re-useable

Again, thank you.

In Ubuntu Linux 18.04, simple console program
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
console;begin  WriteLn('Params: ', ParamCount, ParamStr(1)); 
WriteLn('Press any key');  ReadLn;end. with given option creates a
file "out.txt", and waits for <Enter> to resume (I use View->Debug
Windows-> Terminal Output for input)
out.txt has following contents:
QuoteParams: 0
Press any key

I cannot make it work under Windows.  No matter what I do, it sees the
redirection character and file to redirect to as command line
parameters for the program.
