Certainly C doesn't support case ranges (gcc supports them as an
extension, but using "...", since that token already exists in the
language).  But I'm not convinced EBCDIC is the reason for that.

The lack of case ranges isn't an arbitrary distinction, it's just a
feature that doesn't exist in the language.  That may be a subtle
distinction, but it's significant.

C's switch statement is a very low-level construct, essentially a
computed goto (see also Duff's Device).  BCPL and B both had switch
statements very similar to C's, and neither supported ranges.  I doubt
that the design of BCPL was influenced by concern about EBCDIC.

It depends on what you mean by "objection".  Certainly it's not
valid in current C.  It could be added without breaking anything;
the current syntax is

    case constant-expression :

and constant expression cannot include a comma operator.  I wouldn't
object to adding it to the language, but even if it appeared in, say,
C2020, I wouldn't be able to take advantage of it in code that needs
to be compiled by pre-C2020 compilers.  I doubt that it would be
added, since I've seen no demand for it other than your suggestion,
and it adds no real expressive power.  If someone designing a new
language wants to support a more terse syntax for multiple cases,
that's great; some languages already do.

I wouldn't advise someone designing a new language to use C-style switch
statements in the first place, unless C compatibility is an important
requirement.

My only objection to that is that I find it a bit ugly.  It would
assign a new and very different meaning to string literals.
There's nothing inconsistent about it, but it could cause some
confusion; I've seen code by new programmers trying to use switch
statements on strings.  It adds no real expressive power, and IMHO
it's not worth the cost.

Yet there is a precedent for it in C:

  char str[] = "ABC";

instead of having to write:

  char str[] = {'A','B','C',0};

(although there is the ambiguity of that final 0 which isn't needed when 
used in a switch case.)

The expressive power is in being able to match an arbitrary set of 
characters more easily, where even the range doesn't help. And it's 
easier also to define that string elsewhere, and use it in several 
places including the switch, as well as being able print it or pass it 
to functions.

Something that exists only as case 'X': case 'P': case '.' is less flexible.

Anyway that was just something I thought of while writing that post.

No, that's nothing more than the usual meaning of a string literal.
(It's one of the three cases where an expression of array type isn't
implicitly converted to a pointer.)

When I said it adds no expressive power, I meant that there's
nothing you can express using the proposed construct that can't be
straightforwardly expressed (though more verbosely) using existing
constructs.

As for defining it elsewhere, you could always write:

    #define CASE_UPPER \
        case 'A': case 'B': case 'C': \
        ... \
        case 'Z'

> Anyway that was just something I thought of while writing that post.

If you're going to make switch statements more flexible, you'd have
to reach a consensus on just how far to take it.  Should non-constant
expressions be permitted?  String comparisons?  Floating-point?
Should there be a special syntax that matches uppercase letters
regardless of the character set?

I am not at all convinced, either, though have no direct evidence
either way.

Having learned Fortran long before C, I was surprised after some
years to find out when it isn't.  If you put a 

   case 1000000000:

you find the difference.

If a new switch/case is added to C, I would suggest one like
the verilog case statement.

In verilog, the cases aren't required to be constant, and the first
one that matches is taken. (And no fall through, either.)
(Though most verilog code with case does use constants.)

It could very easily be due to a lack of sleep on my part, but I had
trouble understanding that comment. If you were to expand the phrase
"when it isn't" to "when A is not B", what would "A" be, and what would
"B" be?

What is the difference you found with the following line?

	case 1000000000:

That line causes the value 1000000000 to be converted to the promoted
type of the controlling switch expression. If that's a type which isn't
capable of representing that value, the results can be unexpected, but a
decent compiler should warn you of that problem. In principle, that's
equally true of any case label, though a value that large is more likely
to trigger such a problem. If that's the issue you're referring to, you
should have provided information about the type of the controlling
switch expression. Otherwise, that looks to me like a perfectly ordinary
case label.

A sufficiently naive compiler, given

    case 1000000000:

might (try to) generate a jump table with a billion entries.
(I've seen exactly that problem for the equivalent construct with
a Pascal compiler, though things started blowing up around 10,000.)

I haven't checked, but I'm skeptical that any "sufficiently naive"
compilers in thise sense are currently in production.

It was some years ago when I first tried that.  But then again, 
compilers stay in use long after they are out of production.

I was decoding the high bits of a 32 bit word, such as:

   case 0x10000000: ...
   case 0x20000000: ...
   case 0x30000000: ...
   case 0x40000000: ...

My first use of switch/case was a translation of a Pascal program...

Yes, I didn't make it very clear at all.  Consider:

switch(i) {
   case 1: s="one"; break;
   case 1000000: s="million"; break;
   case 1000000000: s="billion"; break;
   }

I do hope the compiler doesn't generate a 1000000001 entry branch table.
If all the cases are close together:

switch(i) {
   case 999999999: s="lots of nines"; break;
   case 1000000000: s="billion"; break;
   case 1000000001: s="billion and one"; break;
   case 1000000002: s="billion and two"; break;
   }

The compiler might subtract 999999999 and then use a small branch
table on the difference.

You didn't answer that bit, so I'm still confused about it.

That's purely a quality of implementation issue (QoI), and I would
expect any decent compiler to generate a branch table only if doing so
was superior to the alternatives. Given that the equivalent of the
following code is also a valid alternative:

    if(i == 1)
        s = "one";
    else if(i == 1000000)
       s = "million";
    else if(i == 1000000000)
       s = "billion";

It's hard to imagine a compiler validly concluding that such a huge
branch table is a superior approach.
Unless, of course, the required memory is cheaper (in all relevant
senses of the word) than the average CPU time needed to evaluate the
if()s, in which case, what's wrong with using a billion-entry branch table?

If I were going to muck with how switch statements work, that's probably
the first place I'd look.  I've seen a _lot_ of code that would be much
clearer if it could simply switch on a string value.

Sure, I've seen code that could sensibly be implemented using a switch
on a string value, equivalent to:

    if (strcmp(s, "this") == 0) {
        /* ... */
    }
    else if (strcmp(s, "that") == 0) {
        /* ... */
    }
    ...

But very often the required test for each case isn't just a string
equality comparison.  Frequently you really need a case-insensitive
comparison, or a substring comparison, or even a regular expression
test.

The characters 'A'..'F' and 'a'..'f' are contiguous even in EBCDIC.  A
future standard could guarantee that without breaking any systems that
use ASCII-based or EBCDIC-based character sets.

I just don't see all that many cases where case ranges would be useful.
Maybe you see more than I do.

If you want more than that, say 'A'..'Z' to test for uppercase letters,
that might seem reasonable -- but there are potentially lot more than 26
uppercase letters.

ISTM that this is what isupper() is for.  Furthermore, it's not wildly
difficult to gin up a function or macro to do any more complex test you
may have.

I think it would be better in general to lobby for more of these sort of
tests to be added to the standard, rather than making some radical
change to the base system requirements.

For example, when was isxdigit() added?  If there are lots more that are
really generally useful, by all means, let's add them to the standard.

Granted, this breaks a nice switch construct, but I would just do the
isupper() (or whatever) test first, and then put a switch for the
special cases in an else block.

Unfortunately, those functions only handle single-byte characters.

<uchar.h> declares iswupper() et al.  It was added by C11.

isxdigit() is in C90.

And I think many of the really "big iron" systems that IBM sells these

Well a few of them are, anyway.  Having a few Linux images on a
mainframe is quite common, but the actual wholesale replacement of
"squatty box" server farms appears quite rare.  Virtualizing a bunch
of low-utilization servers onto a single physical box certainly has
merit, but a mainframe doesn't really bring all that much that you
can't do with VMWare (and the like).

Well, we don't really agree on the first 128 characters so much
either.  More these days, but things like $ and # in pre-ANSI ASCII
varied between languages considerably.  And we only semi-agree on a
few of the control characters.
