The difference is that TP7.0 has several bugs that are fixed in 7.01.
Unfortunately Borland/Inprise doesn't feel it's worthwile to put the
bugfix on the web. Please complain there. But be prepared to explain
them what Turbo Pascal is, most people there seem to have never
heared of it. Some have reported here recently that it helps to ask
for replacement disks, they are relatively cheap and do contain
the latest bug fixed version.

Re:Difference between TP7.0 and TP7.01


Within the last few months, I was able to download what appears to be
the official BP7.01 update from some obscure web site.  The original
format was probably two 5-1/4" floppys, and it consisted of only the
modified files.  When installed, all the files are stamped 3/9/93,
7:01a.

            Welcome to Borland Pascal with Objects 7.0
                      Maintenance Release
            ------------------------------------------

This README file contains instructions for installing the
Borland Pascal with Objects 7.0 (BP7) maintenance release.
This maintenance release fixes several minor compatibility
problems that have been reported in the compiler, IDEs,
and the Borland protected mode Dos extender, as well as minor
miscellaneous bugs in the demo programs.

This maintenance release contains only the files which have been
changed from the original BP7 file set.  You must have BP7
installed in order to use this maintenance release.  See BP7.DIF
on the install disk for a complete list of all the revised
BP7 and Run Time Library (RTL) files included in this package.
(etc...)

The bug was in 386-specific versions of longint-SHL and SHR which was
excecuted only if the processor was a 386+. It was caused by the
assumption that a shift left by CL on DX:AX could be implemented as

        SHLD DX,AX,CL
        SHL  AX, CL

on a 386+. The implementors were not aware of the (documented) fact
that SHLD/SHRD and SHL/SHR are undefined for CL>=16 if the target and
source are 16 bit objects. On many INTEL processors DX will be 0 after

        SHLD DX,AX,CL

if CL>=16, whatever the value of AX is. On some models it behaves as
expected and DX will contain AX shl (CL-16).
