I was surprized that this does indeed work.  Care to relate that in TP terms
now?  I thought that it would be easy, simply run a COMMAND.COM to run yet
another COMMAND.COM with the /C flag and the output from a .BAT file would be
redirected but it doesn't work:

{$M 16384,0,0}

Program Foo;

Uses DOS;

Begin { Foo }
  Exec ('D:\COMMAND.COM', 'D:\COMMAND.COM /C C:\ANDY\FOO.BAT > FOO.OUT');
  Writeln ('DOSError = ', DOSError);

End. { Foo }

Where D:\COMMAND.COM is a valid COMMAND.COM and C:\ANDY\FOO.BAT contains:

DIR

When this is run I see:

Specified COMMAND search directory bad
DOSError = 0

written to the screen and in examining FOO.OUT I find simply:

DOSError = 2

Now what am I doing wrong?
