hi sreenadhs
with normal compiler like turbo c you can't change because the compiler designers restricted the access to modify them due to system instability errors,if you are working on controller you can change the Program counter value refer "debug architecture" chapter in "Definitive guide to cortex-M3" book. hope this might helpful to you.
Thanks and Regards,
Harshan
