Hi Jeremy,
the two problems I found were to do with char and accessing string[0].
string[0] : I ended up doing a global search through the whole app for
[0] and fixed every one of them.
char : unless you are careful, I found that even though the code
compiles, it does the wrong thing to what you expect - I had to inspect
each usage of char and sort its type.
I have CRC routines. I am still using shortstring in them. And the
unit testing passes.

HI all.
I have a Delphi 2007 application that I NEED to upgrade to Delphi XE 8
or greater.
The problem is, I am having trouble converting the code due to the
fact that Embarcadero changed how "String" etc. is used when they
added the support for Unicode.
I have had a couple of cracks at the conversion and I am "close" on
one project but I am starting again because I want to make sure I am
using the right variable types and not guessing.
There is a bit of MD5 conversion going on and the different variable
types of course generated diff MD5 codes for the same string being
converted and it is a bit confusing :-)
The main variable types are:
String
Byte
Integer
LongInt
Pointer
Array of Char
PChar
Char
My understanding is the variables should now be :-
String = AnsiString?
Byte = Still Byte?
Integer = Still Integer
LongInt =Still LongInt
Pointer = Still Pointer
Array of Char = PAnsiCHAR ?
PChar = PAnsiChar?
Char = AnsiChar?
Am I correct with the above that I have highlighted in "Red" ??
Thanks, Jeremy
