This is simply wrong. If a language (not A68, but using its syntax)
REQUIRES you to write this:
[n]INT a = (x1, x2, x3, .... xn)
That is, the 'n' has to exactly match the count of items, then that is
very poor. There are several issues
- Finding out what N is in the first place
- Having to keep N in sync with the number of items, as things change
during development
- Having to either hardcode a literal for N, which is usually a no-no,
or needing to think up a name for it and define it separately
You seem to be dismissing that first one. Even if it is trivial to work
out, why do you need to bother? It is much better to just allow [] and
then it doesn't matter what the count is.
My data could have been all on one line. It could been read from an
external file. That could have been generated from a process which is
part of a build-script (LD'O's suggestion), then you will not know what
it will be before you start to build.
There some instances where you do need a count (for example it has to
match something else in the program) so you can /optionally/ supply it,
and the compiler can report a mismatch if the item count is wrong.
Otherwise, things can get very tedious if you have to get ? exactly
right here:
char message[?] = "<some long string literal>";
Some have better things to do!

I mentioned embedding binary data, in cases where the language doesn't
have such a feature built-in. There are utilities that can convert a
file into a data-block suitable for a language such as C. Eg. my example
will work in any language that accepts hex literals, or it could simple
have used decimal.

Most scripting languages can deal with strings, and those can be large,
eg. Python:
a = "A" * 100_000_000
print (len(a+a)) # 200000000
I assume they can include binary data including embedded zeros.
If A68G can't do that, then it's a QoI issue.
