Hello again,
I have another question and i hope you will understand me..
Is there any option where you can set the program to go back to lets say the top of the code?
I mean if the program finished the operation and i want to stay in the program and go back ro the start.
after any operation i want the option to do it again , go back to the main menu or full exit from the program, and i want it every time.

i hope i'm clear :)
