No contradiction here: the corresponding implied subrange goes from lowest to highest assigned value, which is 0..n for dense enumerations and low(consts)..high(consts) for Enumerated Types with Explicitly Assigned Ordinality. There is nothing special about the holes, they just have no names. This is also how the Delphi debugger displays them. Again, I recommend reading the TP5 and TP7 books, which contained the *rationale* for most of the type system. That got left out when they rewrote the content for Delphi Help. -- Regards, Martok Ceterum censeo b32079 esse sanandam. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
