Input "wrong" answers
Posted: 03 Feb 2021 05:48
Hi, I'm very much a newbie here, and cant figure out how to solve a problem.
I have written a batch program with two segments
I've then managed to get a simple user input to ask which direction the copy is to be made.
All of this works as I want it to, but I cannot figure out how to deal with "wrong answers".
If I ask for input for example "Copy from A-B or B-A" and look for answers "A-B" or "B-A", how do I reject any key input other than those 2 options?
Incidentally, I haven't decided on the actual wording I want to use for input. This is example text only, I feel "A-B" or "B-A" are too similar and liable to confusion (although the program cannot do any of the copy or move if the wrong direction is selected).
Hope someone can help. Thanks
I have written a batch program with two segments
- to copy a single database (Lightroom photo database) file on my desktop PC, and rename it with a date/time before moving the original to my laptop
- to reverse the process
