Sometime sit is important to some people that : they demonstrate to as many people as possible : that yes, they can be an a$$hole instead of a civil person. I've made that suggestion multiple times, and it's been ignored. If you didn't read those replies from me...oh well, what can I do? I'm sure if you Google "Google is your friend in this regard", it'll come up a few times. As as far as your opinion of me, I tend not to lend any real credibility to those who go out of their way to remain anonymous...I don't care how helpful or "knowledgeable" you are. If you want to label me, do it to me under your real name, man to man. Otherwise it's a coward move. You also should know this by now. At least numbwits like Paul and Tom have the balls to use their name to take their swipes. What's your excuse, besides being "Nobody"?

Some topics just never, ever, die. Here's a little more fuel for the "don't use it" fire, still unchanged since some time last Century: http://obob.com/cis58/evilend.html It appears to still be the #1 result, if you google "The Evil End Statement" (with quotes), as it probably should be.

Syntax 1 END [[{ DEF | FUNCTION | IF | SELECT | SUB | TYPE }]] Syntax 2 END [[ n% ]] Remarks There are a number of ways to use the END statement, as described in the following list: ------< omitted all remarks about Syntax 1, not relevant here >------ n% Ends a program and returns the value n% to the operating system (if n% is omitted, the value of n% is set to 0). END is not required at the end of a program. The value n% can be used by DOS or OS/2 batch files or by non-BASIC programs. Untrapped errors and fat5al errors set the value of n% to -1. By itself, the End Statement stops programm execution and closes all files. In a stand-alone program, END returns control to the operating system. In the QBX environment, END returns to that environment. You can place an END statement anywhere in the program to terminate execution. ================================ As you can see, END was not always the tree to stop the car abruptly. BTW, the VB-DOS Language Reference contains the same remarks about END. And the Language Reference for Visual Basic Programming System for Windows (that's VB1) states [translated from my german edition]: "The statement END stops program execution, closes all files, cleares the values of all variables, and deletes all forms. ... Pay attention to END not causing a Form_Unload event." So between VB-DOS and VB1 we lost the n% parameter, but VB did still all necessary clean-up. Then there came a paradigma change. Basic was known to shield the programmer from messy details and do it "under the hood". Now we had to close database connections, unload all forms, set all forms to Nothing, destroy all objects... instead of enhancing the functionality of END to do all that for us. END now became EVIL.
