But not for all characters being written to the stream, only for the
characters that the library itself produces when writing floating point
values, hex values, etc.

It's not in the standard either; nouppercase doesn't seem to be the
equivalent.

In the standard, the manipulator you want is spelled "nouppercase".

A "lowercase" would be different from the "nouppercase".

I find that whole section of the standard confusing, but I think that
nouppercase turns off the conversion of lowercase characters to
uppercase; it doesn't cause conversion of uppercase characters to
lowercase.

There is no "lowercase" flag or manipulator in the standard.

If the "uppercase" flag is set, uppercase letters are used for hex
and floating-point numbers, e.g.: 0X1234, 1.2E34.

If the "uppercase" flag is not set, lowercase letters are used,
e.g.: 0x1234, 1.2e34.

The standard specifies the manipulators "uppercase", which
produces the first result, and "nouppercase", which produces
the second result.

A "lowercase" flag would be redundant, since one bit is sufficient
to choose between two alternatives, and there are only two. That
is why the standard does not specify a "lowercase" flag.

You might argue that "lowercase" is a better way to spell the
manipulator that causes lowercase letters to be used, but the
final C++ standard prescribes the spelling "nouppercase".

There is no iosbase::lowercase. In this situation nouppercase is exactly
what's wanted, because these only affect things like the 'x' in
displaying hexadecimal values and the 'f' in displaying floating point
values. Specifying nouppercase does not result in mixed case, it results
in lowercase.

There is an "uppercase" manipulator:
    ios_base& uppercase(ios_base& str);
    The manipulator effectively calls str.setf(ios_base:: uppercase),
then returns str.
But there is no "lowercase" manipulator.

Is this an omission of VC++ 5.3 or is missing from the standard too?
