I am trying to spawn a process using Turbo C 2.0 where
the executable I am spawning requires the pipe character <
to define an input file.  In other words, on the command
line I would execute the program as follows:

progname < inputfil.txt

Within my program, I have tried to call the progname.exe
executable by using the spawnle function as follows:

spawnle(P_WAIT,"progname","progname","<","inputfil.txt",NULL);

With the spawn function shown above, the progname program
complains that "<" and "inputfil.txt" are invalid arguments
yet when I run progname from the command line it works fine.
Other arguments that don't use the "<" character work fine
with the spawnle function.  Any clues as to how to do this?
I'm assuming that since the "<" character is really a DOS function,
spawn doesn't know how to handle it.  I would also assume that
the same problem would be had with the "| more" addition to
some commands.

Thanks for any help,
Dave

I've had a similiar problem using spawn with PKZIP and it's comment
argument "z<comment.txt". The only way I found to go around it was to use
the system() function instead along with an sprintf() to include the whole
command line in a string. If you don't need to examine the returned DOS
errorcode, I don't see why it shouldn't work.
