A examle of MEMORY RESIDENT PROGRAM (Now zip file included)

I think who wants to write TSR, will get some help from this program. anyone can also know how to use VDU memory directly. This program changes existing texts color of the DOS in every 10 second with 15 random colors. NOTE: I compiled this program with Turbo C++ 3.0. Please run this program in DOS mode and wait 10 seconds to see action. It changes color in every 10 seconds. To know is it in the memory or not, write this in command prompt mem /c/p Thank you.
