I am writing a program which must be able to execute another
program from within my program, based upon a user supplied
command.
 
Using DOS function 4B works fine. For a while, I was merely
using it to invoke a second copy of COMMAND.COM (god, I wish
MicroSoft had seperated the code & data segments so this wasn't
necessary). Anyhow, if I use function 4B to invoke a second
COMMAND.COM, my specified command can use redirection.
 
BUT, I decided I would try to eliminate the overhead of loading
COMMAND.COM when a program was being invoked. Well, suprise! If
you run function 4B to load a program which has redirection on
the command line, it doesn't work!
 
Could someone please tell me how I can inform DOS apriori that I
wish all standard output (or input) to be redirected? Is IOCTL the
way to go? If so, how is it done?
 
Any help would be much appreciated. Thanks.
