RE: Procedure and Function (Rambling thought)
A function must return a single value. What language uses functions that don't? This is a bit misleading. While most languages limit what functions can return to a single variable, that variable may well be a complex data object, like an array.

Re: Procedure and Function (Rambling thought)
I kinda think the new CF functions as poor man's objects without the protection and inheritance stuff. I don't agree with the fact that objects are too complex are not suited for scripting languages. If used right, they actually save tons of work/time long term and can actually make our programs run faster especially if the app is pretty large in scale. After all, objects are created to ease our programming headaches if used in the right places. CF/Allaire want to capture the enterprise market which is why they have all the loadbalancing intergration so that they can make huge profit margins on the Enterprise editions and the bloated/hugely complex enterprise level projects demand objects to make life a lot easier. I wouldn't be surprised if the spotlight feature for CF 6.0 (hopefully the JSP/pharoh? version) would be objects. It's just a matter of when not if in my mind. xing - Original Message - Subject: RE: Procedure and Function (Rambling thought) I agree! I dont know what the big fuss is about... CF Tags are functions as far as anyone should be concerned - just because they're not implemented in exactly the same way VB, Java, etc implements functions means didley squat... I'll be the first to admit that I'am sometimes frustrated by how CF Tags are carried out but more often then not i thank god that they work as they do, it makes life so much easier when your output is HTML. As for objects - Anyone thinking of using a scripting language to create a program that requires objects should be taken out and given a good talking to. CF is great as the glue that holds together all the objects that we need to create effective websites (DB connections, Email, Files, Forms, etc) but by no means would i use CF to create something as complicated as a credit card transaction gateway - Java is much more nicely designed to do this. In short, i think CF has been brilliantly written to create websites quickly, effectively and under budget - an equivilent website could take as long as 3 times longer if written in C++ or Java... The right tool for the right job - you dont complain when your drill doesnt perform well as a hammer.

RE: Procedure and Function (Rambling thought)
A function must return a single value. What language uses functions that don't? On the other hand, you're write about procedures. However, procedures are (were) often used to modify values of the passed parameters, which is what I was referring to below.

RE: Procedure and Function (Rambling thought)
Another rambling thought follows: Haryono my apologies, your question wasn't exactly the same as the original one. You can USE procedures and functions THROUGH any of the extensability that CF offers, CORBA COM Java C++ Delphi Although cf has no concept of a 'procedure' or 'function'. It does have an equivalent, 'tags', it is a tag based scripting language, making it easy for people to not think to hard about things if they dont want to. Jared Clinton.
