I hate "with" with passion because maintaining code written using it (by other people ;-) ) is very often a living hell. I, for one, always use local variables in that case, but I'd really really love to be able to declare an alias for "with" expression, no matter how many people say it's unpascalish... WRT a "safe with", well, the compiler could continue the identifier search as if it didn't find in the With expression and then generate an error or warning... -Flávio -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
