How to skip error and continue (NOT in loop)?

If I have the following code, how to display x(10) after x(9999) causing an error?
x = ones(1, 10);
try
x(1)
x(9999)
x(10)
catch ME
fprintf(ME.message)
end
The output I got is:
ans =
1
Index exceeds the number of array elements (10).
Thanks!

x = ones(1,10);
idx = [1 9999 10];
for K = 1 : length(idx)
try
x(K)
catch ME
fprintf(ME.message)
end
end

A = command1thatcanpossiblycauseanerror;
B = command2thatcanpossiblycauseanerror;
C = command3thatcanpossiblycauseanerror;
D = command4thatcanpossiblycauseanerror;
% etc
That has a similar code smell to the frequently asked question about dynamically creating variables with numbered names like x1, x2, x3, etc., for which the general consensus is to avoid doing that.
Rather than posing a hypothetical scenario, can you share a little more detail about your actual application where you use a pattern like that code? What do those commands that can possibly throw an error do? Are they independent or are the outputs of one or more of those functions the inputs to later of those functions?

I am having difficulty thinking of any code that is such that
A = command1thatcanpossiblycauseanerror;
is valid code, but
for dfpSzcGKKqyMbgIcvYXqkicEiRRKtIUpb_vjDshBQupYrSfhm_GS_xNidaex = 1 : 1
A = command1thatcanpossiblycauseanerror;
end
"cannot" work.
The only things I can come up with are along the lines of "needing" dbstack to be able to pinpoint the function name... ummm, no, even that would not explain things.
