Problems with Activ Ada in Windows NT

Problems with Activ Ada in Windows NT

[Fabrizio Castrotorres]

hi,
recently I started using the Activ Ada compiler for windows NT
This product is obsolete and unsupported, replaced by ObjectAda
which supports only Ada 95. The projects I need to work on require 
a compiler that supports ada 83 in its full capacity.

I started doing a program using the Old Windows 3.1 Activ Ada Compiler
When I got the NT version I took the source code and compiled it
with the NT version, it compiled with noerrors same as the other version
however when It write files to disk it does not print out the
same number of bytes.
It stops in the middle of a word and goes no further.
I have not changed the source code in any way.

What could be causing these incomplete file writings ?

Any help would be greatly appreciated.
Thank you

Ada 95 is very nearly 100% upward compatible with Ada 83.  I've heard
of one project consisting of several tens of thousands of lines of Ada
83 code that was ported to Ada 95 with no changes.  You should probably
consider obtaining a supported Ada 95 compiler for your projects.

We probably won't be able to help you without more detailed information.
How are you writing files to disk?  Direct_IO?  Sequential_IO?  Note that
the language doesn't specify exactly how the predefined I/O packages write
files to disk.  You *might* be seeing the effect of a slight change in
the internals of the I/O package you're using.  If you can read the file
using the same package used to write it, you're probably ok.  Are you
having problems with files written by an older version of your program?
