The general way to do this should be to close the output, and to reopen
it to the redirection file

  close( output ); assign( output, 'redirect.fil' ); rewrite( output );

This should make the DOS handle for standard output point to a file
instead of the console. When executing a child program this
redirection is inherited. The same can be done for input and error.
If this doesn't work it may be nessecary to do some direct acces to
DOS.

I do not guarantee that this works but try playing with it, and if it
fails let me know and I will find out for sure how it is done.

BTW make sure to test on a program which uses DOS for output and not
BIOS or direct screen access.
