Here are some questions on bug/feature of Zortech C++:
(1) overload &:
friend String operator&(String&, String&);
will cause compiler error. (found in compile libg++ String.cc).
This is a bug.
(2) initialize parameter:
class foo {
int foo(int i=0);
};
// and later:
int foo(int i=0)
{
//code body
}
this will cause compiler error, redefine initialized parameter. (sort of)
will C++ 2.0 accept this?
(3) sometimes the error message list wrong line number.
overall zortech c++ 2.0 is a much improved product, I am happy with it.

Did you mean that (a bunch of errors) or: class foo { foo(int i=0); }; // and later: foo::foo(int i=0) { //code body } ?? which cfront 2.0 doesn't like either since it assumes (I think) 'i' is being initialized with 2 different unique values. -- Greg, Comeau Computing, 91-34 120th Street, Richmond Hill, NY, 11418 Also, mag writer for UNIX Today!

Fixed in 2.06.

This behavior is as defined by the DRM.rchen@m.cs.uiuc.edu (01/09/90)
Here is another Zortech C++ 2.0 bug:
class Choice {
// ...
public:
Choice(char*, ...);
// ...
};
main()
{
Choice a("first", "second", "third", "forth");
// ...
}
The above program will cause a "compiler bug: nnnnn" error. My program
worked fine with Zortech C++ 1.07, though. I wish Zortech had a nice
bug-fix policy, so that I can get the patched compiler faster
and easier. Don't tell me to wait for another release as I did for
version 1.07 when I reported several problems with 1.06.

(My temporary patch is to overload the comma operator, and add extra parentheses to compensate for the lower precedence. Ack!) Zortech must be shipping a lot of C++ compilers. The package I received was labelled 3" media, and I had ordered 3-1/2" media, but the box was filled with those damned 5-1/4" suckers, with the diskette package seal already broken. I expected <iostream.h> and <complex.h>, but neither is included in the product; and <stream.hpp> is badly broken, returning _eof one character too soon. That's right, #include <stream.hpp> int main() { char c; while(cin.get(c)) cout.put(c); return 0; } does not completely copy stdin to stdout! (I believe the error was in streambuf::sgetc peeking at the next character to determine whether to set _eof.) There are other buffering problems as well. Sigh! The compiler also bitches at files that do not explicitly end with a newline, although ZED occasionally generates such beasts. Why is this a lexical error? Installation went smoothly, and the compiler is very fast, but I'll reserve judgement until I have all the work arounds to get my code working again. ----- distressed, jeffa

Well, I wouldn't say that made it badly broken. In any event I think the problem is in the snextc routine and somebody on BIX has posted a solution of some sort to the problem. -- Greg, Comeau Computing, 91-34 120th Street, Richmond Hill, NY, 11418 Producers of CC C++, SysAdm columnist for UNIX Today!, Microsoft Systems Journal (C programming), + others.

If there is a fix to a problem with Zortech streams, and it's nottoo large,
please post it here somewhere. Walter?

Did you get 2.06? If not, call them and request the update.

Because ANSI C says it is. (I don't personally agree with it, but am
stuck with it.)Roy.Browning@f713.n106.z1.fidonet.org (Roy Browning) (01/17/90)

Jeff: To enable a program to import more than one string from the console at a time I modifed <stream.hpp> in the following manner and recompiled the libraries. int sgetc() { return (gptr + 1 < pptr) ..... } The propblem was that sgetc() was continuing to point at the previous input even when called anew.

Dear Mr. Bright, I received the Zortech C++ 2.01 from Zortech Central
also. I called them and asked about 2.06 and they denied it exists. What's
the magic incantation to get through to someone who knows what they're talking
about at the home office?

I called Zortech on Jan 20th, and they told me that they were shipping 2.0 with bug patches included with the shippment. I asked about the version number, and the reply was 2.06. The lady I did talk to however, said that they were getting a shipment of fixes on disk to send to registered customers in the next week. I assume that this is 2.06. The next day, she called and said that the fixes would be sent with my order, and NOT in a couple of weeks. I does seem like someone(s) don't have the correct information.. -Mark

The 2.06 update is being shipped free to all customers we know about. If you
bought it from a dealer and didn't send in your registration card, then
obviously we don't know about you. In that case, call Zortech and request
the update. As to denying it exists, that must be a misunderstanding. Please
try again.
P.S. Send in those registration cards!jb@altair.uucp (John Birchfield) (02/16/90)

I guess maybe youse takes your chances when you call the Zortech office. I would assume that everybody else who got 2.0 will also receive 2.06 automatically. +---------------------- | John Birchfield | jb@altair.csustan.edu +----------------------

Not quite true. If you bought from a third party dealer, and did not send
in your registration card, then Zortech has no way of knowing who you are
and so cannot send you the update.
So send in those registration cards!
