hi guys,
actually i am trying to make a small program that will replace an old program .
now the old program is used in hundreds of batchfiles and strangely it works fine with those characters.
am not sure what that program is made in ,maybe C++ .
so was just wondering if that program works without using " ,how come my program cannot detect those characters.
am only trying to avoid changing all those batchfiles.
thank you for your help so far

If you send a commandline to it from a batch file with > characters in then it will redirect output to the filename after that, period.  Could it be that the old program isn't reading that parameter but is actually just outputting to the console and the > whatever is creating a file called whatever that is then used somewhere else?

If you understand all about redirection using > < >> << | 2> 2>> etc. then sorry, ask if you want to know more!

i.e. do your batch files do does stuff like this?

myexe.exe hello > afirstfile.txt
myexe.exe something else  > anotherfile.txt

then processing output that is in afirstfile.txt and anotherfile.txt

Don't know why I am bothering answering anyway because I followed a link from the MSDOS area but of course on this stupid website this is really in Delphi, points no use to me here!

Hi guys ,
thanks once again for spending time to help me.
I understand what you guys are trying to say but there is one thing wrong with what you are saying.

if i have a batch file and I put something like
myexe.exe hello > afirstfile.txt
myexe.exe hello > asecondfile.txt

there is no way the program can redirect data to afirstfile.txt and then read it because it just cant read anything after > so it does not know which file to redirect to and then read ,which is the exact problem i am stuck with.

I hope I am not confusing you guys

Thank you once again for your valuable time

Most of the characters are readable if you first surround them with double quotes:
  Prog.bat     "C:\File.txt"
  Bat.cmd       "Program.exe/s MyFile.dat  > Output.txt"

Everything inside of the quotes is a part of the same argument and can be passed as a complete string

> myexe.exe hello > there

the word "there" is translated into the filename for your output via redirection

>  it seems it looses > there

not lost, it is interpreted for you for execution

just in case this helps ,
the freeware program i am trying to imitate is here

it works with > in batch files , very amazing indeed

> I hope I am not confusing you guys

I am

I doubt you need:

MyExe  >   Log.txt
MyExe  >> Log.txt

Try this as a batch file:

echo hi >     Hi.txt
echo hi2 >   Hi.txt
echo hi3 >> Hi.txt

This is appending, which is similar to have read original file before adding to it

?
You also want input?
From a file?
From the keyboard?

>>there is no way the program can redirect data to afirstfile.txt and then read it because it just cant read anything after >


see my example again, can you see there somwhere checking params or lookng for file name?

>>the freeware program i am trying to imitate is here

didn't download file well I think I don't have to....
"(...)Example:
Winput "SET Name=$input" "Please enter your name" > temp.bat
if not errorlevel 1 call temp.bat

This will send a set statement to the file temp.bat,(...)"

as you can see here's everything we told you,  you have parameters in quotes and REDIRECTED output to temp.bat "This will send a set statement to the file temp.bat"
