PosEX dosn't work on 64-bit

[rlebeau]

By example:
PosEx(':','C:\SVN\Mydirectory',3) return 2 (that is the right value if I call PosEx(':','C:\SVN\Mydirectory',1))
while it must return 0 (as 32-bit does).

That is something you need to report to Embarcadero, AToZed has no control over those RTL functions.

FWIW, I can't reproduce what you describe in Delphi 12.  PosEx(':','C:\SVN\Mydirectory',3) returns 0 in 64bit, as expected.
