Yes this is a very important distinction however the compiler you were
using accepted char *argv[] but ORCA/C did not.  Your explanation clears
this important distinction.

assistant: Hi Thomas,
The moderator will pull you up on this but this is a real names only echo.
You are fortunate, this is an almost valid C feature too! Look for for an
echo with the tag C_PLUSPLUS for a purely C++ group.
Firstly because you are declaring a pointer to the structure there is no
infinite loop. Secondly, this kind of thing is mostly useful in linked lists.
For example:
struct  _line{
    char    *data;
    short   flags;
    struct  _line   *next;  /* nb. struct keyword is req. in C */
}
This is an example of a structure that a text editor might use. data pointing
to the actual line text and next pointing to next line.
You could also have another pointer pointing to the previous line which makes
things easier to deal with.

You should have received it by now. I had another quick look at the PCC TSR

not work properly where the size of the environment is greater than 256, so I
did not pursue it beyond that. It might pay you better to look at loadable

Hi George,
Insertion sort is faster than Shellsort?  I have to express some skepticism
about that, or did you exclude Shellsort from your tests?
[Switching from C to English]
No. I think the pronoun is in the dative case in that context.

I have already coded a template for that algorithm and will be posting it in

assistant: Hi Sean,
There has been a lot of chatter about sorting recently. Your sort rout. seems
to be sorting by ascii code. You should be converting to numerical and
sorting from there. The easiest to do although probably not the best is a
bubble sort. Basically go through each element and compare it to the next if
it is out of order, swap it, continue this until you the list is in order.

assistant: Hi ``Tical``
Well In C you have struct's too!
Well, I think, that struts are powerful, similar to a record in pascal.  What
is the point, well, it allows you to keep all assocaited data in one place.
Say you were writting a database, it would be convienient to have all the
fields of each record of your database where you could quickly lay your hands
on them.  so:-
struct  DB_RECORD
{
  char sname[12];
  char cname[12];
  char addr1[12];
}db_record;
DB_RECORD current_record;
so when you wanted the cname in the current record, a somple
printf("%s",current_record.sname);
would do the biz for ya!

Yeah, it's been awhile, eh?  However, I have additional comments after seeing

Yep.
Also, I'd submit that it would be wise to keep the __STDC__ macro instead of
using the USE_WILD macro since it's standard C that prevents using wildcards
(among other things).
I also don't understand why you needed to add a prototype for the toupper()
function as it's a standard C function -- this would be a problem with your
compiler rather than the code.   I can't recall if I coded those calls with
parentheses [ i.e., (toupper)(ch) ] but I normally do since this forces the
functions to be used instead of the allowable macro versions (I've had some
problems using the macros in combination with some optimizations).

    Not in any of mine, it isn't, but stdio.h is entirely hardware and
operating system dependent, so it varies from one implementation to another
and it's nothing to worry about.
    At last I understand what you were talking about. :-) For Ms-Dos I just
include "device=ansi.sys" in config.sys and Bob's your uncle. Works like
magic every time. Pretty colours, cursor control, windows, the lot! Try that
first.
    If that fails, write your own cprintf() in assembler. It's not
impossible. :-) It's not even particularly difficult. :-)
    I don't know anything about Borland. I always leave those questions to
George. If he ever starts making mistakes, then there's others here equally
competent. I have Microsoft (umpteen versions from QC up to the full Monty),
SDK, IBM (for OS/2), Zortech, PCC (including source), MIX, Cromemco, and
there's a GNU archive and the bog standard BSD unix C if I care to dig them
out. There's also a Lattice C, a tiny C and Whitesmith's C for CP/M and CCP/M
about somewhere and some yacc and lex files on floppy disk in the garage, so
you see - I don't need it.
