Here is a situation. I have received a maintenance change
request on one of the program.
While I am making changes to the program, one of my friend pops
in and I leave with him for a cup of coffee without SAVING the
changes I made.
After few minutes , when I am back, I am not sure what changes I
made previously on the program?
How can I find the changes I have made (without getting out of
there is any command line to achieve this...
