Most cases have analogous format as case 10, so I only pasted case 10.
It seems that the first two statements are skipped, no matter what they are,
while the case number is above 10.
Therefore, I thought that the problem may be caused by the codes in case 10,
but I can not figure out how could this happen.

I encountered a strange problem about switch-case statement.

When the cmd is above 11, the first two statements are skipped. Take case
11
as example
the first executing statement is S3, not S1.
What the problem is?
I've no idea, and it would be very hard to tell without seeing your
actual code. For example, what _are_ S1, S2, and S3? How is cmd defined?
What is the case just before case 11? Show your real code, and we may be
able to help.
