on this forum that uses xcopy to capture a keystroke. I've tried it with echo on and
it looks like it should work, comparing entries with valid choices, but results are not
Choices are 1, 2, 3 or q.
If I enter 1, it tests to be invalid. If I enter 1 again, it is a valid choice.
If I enter 4 (not a valid choice) it tests to be a valid choice, and if I enter 4 again,
it tests to be invalid. If I enter q, it tests not valid but proceeds to quit anyway.
This batch code is just to explore how keystrokes can be trapped, and I hope with your
help, will evolve into a bug-free function.
Thanks for your advice and any other tips about this CHOICE alternative.
