Declaring array of length 1

[Tricky]

I have the following array:

subtype level_t is natural range 0 to 4;
type levels_array_t is array(natural range <&gt of level_t;

then as a generic I have:

createLevels : levels_array_t := (0, 1, 2, 3);

This is fine when the length of the array is 2 or more, but I when I
try:

createLevels : levels_array_t := (4);
I get the error:
** Error: Integer literal 4 is not of type level_array_t.

How can I declare a literal array of length 1? even trying the
following doesnt work:
createLevels : level_array_t(0 to 0) :=(4);

using positional association...

try:

createLevels : levels_array_t := (4);

Use named association for this
createLevels : levels_array_t := (0 => 4);
or even
createLevels : levels_array_t := (others => 4);

Here are two methods...

createLevels2 : levels_array_t := (0=> 4);
createLevels3 : levels_array_t(0 to 0) := (others => 4);

This ^^ wouldn't work because 'createLevels' is an unconstrained
array.

oops, another brain fart on my part. For a single-element (constrained)
array, it would work. As in your createlevels3 example.
