Many thanks to Jim Holtman and Gabor Grothendieck for your quick responses. Jim's solution works beautifully for my tasks. Thanks. I also tried Gabor's solution based on pipe(). Unfortunately it only works on a linux PC, not on Windows 7/Vista. Submitting the command in Windows results in nothing. I suspect that it is because pipe() function behaviors differently in the two systems.
