[fpc-pascal] {$J} default setting for today
Hi, I read this: http://www.freepascal.org/docs-html/ref/refse10.html "Support for assigning values to typed constants is controlled by the {$J} directive: it can be switched off, but is on by default (for Turbo Pascal compatibility). Initialized variables are always allowed." Then I read this: http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/devcommon/compdirswriteabletypedconstants_xml.html "In early versions of Delphi and Object Pascal, typed constants were always writeable, corresponding to the {$J+} state. Old source code that uses writeable typed constants must be compiled in the {$J+} state, but for new applications it is recommended that you use initialized variables and compile your code in the {$J-} state." I think we should follow Delphi in this case. Typed constant should not be writeable by default. That's what a constant should be. The old behavior is a flaw. At least let {$J-} be the default for {$MODE DELPHI} and {$MODE OBJFPC}. What do you think? –Mr Bee ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

It can maybe be changed for {$mode delphiunicode} Jonas ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

If it was originally implemented for Turbo Pascal compatibility, why is it enabled for ObjFPC and Delphi modes?
