I dunno it is a religious thing, read the other messages too :) I guess too many underscores in the code I find messy so I've fallen for the 'A' prefix now. I use underscores only where there is really a need, and have found that too many of them in code causes messiness and hard to read code. Either solution is okay, but since there is lots of existing Pascal code out there that uses the A prefix, it's probably best to use it. I'm not stubborn and am willing to change for the better. I do prefer underscores in very special special cases, such as when you have a very similar function but it does something special in addition to the other function: Parse (input: string); Parse_SF(input: string); SF stands for secure and fast implementation, whereas ParseFastAndSecureImplementation() is way too long, and you cannot tell whether it is Parse Fast, the secure implementation or Parse the Fast, Secure, implementation or Parse, and please do it securely and fast Also ParseFastAndSecureImplementation() looks extremely different than Parse() whereas Parse_SF looks extremely similar to Parse() so you know that Parse_SF() and Parse() are two similar functions, with one just being special. So the underscore helps suffix and separate function and keep the code logical without being extremely verbose. This is the sacrifice I've made for making underscores useful in some areas - some prefer to skip underscores altogether for religious reasons, I prefer to include underscores in code when they have some extreme advantage. And the brackets? Yes I know it is a sin in Pascal to use Procedure() and only Java programmers do that, I was just using the brackets in this text so that the text was easier to read, i.e. distinguish Pascal procedure from English text. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
