Because I couldn't find any documentation saying this should work and I 
wasn't sure if this worked by luck or design.

Yes. I know you've said that, but the problem with such a statement is 
that it only applies to what is supposed to work and undocumented 
features that worked in the past may no longer be valid once the 
implementation has been updated.

While the online documentation says a lot about tyepcasting PChars to 
AnsiStrings, there seems to be nothing on the reverse.
