Ok, not the reason. But coding security is the reason, you should do so, if you can. Look at Stroustrup. The reason for pascal not to do so, is what follows from that, a really complicated stack unwinding, for example.
Stack unwinding is not an argument, IMO. C++ and OPL have managed data types, that require proper stack unwinding. But there is no requirement that stack unwinding has to recurse down into local code blocks, since the compiler is free to collect all managed variables into one memory block.
The use of local variables at block level has other consequences: + every loop could use "i" for the loop variable - the user (or IDE) has to figure out the declaration of every "i" DoDi _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
