Write your reply.

assistant: Sounds liks you're doing a dictionary counting sort of thing.
The way you have it setup is going to be very inefficient for searching and
storage.  A better way of doing it that takes a little longer for insertion,
but much less time to search, etc. is to create a tree structure based on the
contents of the char array.
For instance, if you had the words "add, aditional, bump" you could make a
tree which looked like
              (root)
        +------+  +-------+
        a                 b
        |                 |
        d                 ump
     +--+--+
     d     itional
At each end point, you have a counter which stores how many times that word
has appeared.
When you go to insert, you follow the tree down until you either find the
word you're inserting, or you can't find a sibling which contains the data
you're looking for.  In which case, you insert the sibling node and make a
new part of the tree.

 There is some code in Snippets that may help.

can do to go from file->Screen

    A pointed point ... verily. :-)
    I graciously decline your kind invitation, Bruce, because you omitted the
array name<->pointer interchangeability concept. It does exist, but the whole
purpose of my lengthy and laboured example was to show that all such
arithmetic depends on what the elements are. :-)
    I.e. the point was to point out that it all depends on *what* the pointer
points to, not *where* it points. :-)

    For everybody else's benefit John and I have been talking about where.c
in netmail. I've now sent him a version that isn't yet thoroughly tested for
MicroSoft C, but it does seem to find and print all matching files in pretty
colours if you have ansi.sys loaded. MS graphics are too way-out and too far
from the mainstream for me to attempt use graph.h and swap to graphics mode
for such a simple utility.
    If and when John gets back to me, we can thrash out the bugs in the code
here in the echo, and address the portability concerns in public after we
have had a chance to find out what they are in private. :-)
Best wishes,
Bill.

This, my friend, is as far as I am concerned a bogus claim. I have never
heard of, nor seen any Linux backend for the MSVC compiler and I very much
doubt we will ever see one, which is not so unreasonable if you take
Microsofts attitude towards rival operating systems into account.
But still, I am not mister perfect, and I could be wrong of course. So,
please, provide us all with ample supporting evidence that indeed there
exists such a thing as a backend for MSVC which will generate binary object
files and ELF executables for use on the Linux platform.
Looking forward to it, or, as Dirty Harry used to say: "Make my day!" <g>
