The Weird and The Wonderful

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

That's a bit harsh isn't it? Used in the right place, a trick like this could shave days off a long simulation run on a research cluster.

Finding the right place to use something like this is always the hard part.

Yeah, there's some optimization for ya. Instead of typing a nice little two letter word like if, now you have to remember a ton of 3 letter "if" statements that all being with "J". Wink | ;)

I would suggest that you learn what automated profiling is. Then buy or find a tool that does that. Then learn how to use it effectively.

I'm definitely a beginner but I have a question:

Doesn't the program end up doing an if/then regardless of whether or not you're removing the actual syntax? There still needs to be a comparison done somewhere, or at least I thought.

The old IBM 360 JCL didn't have any if statements.

In PERL, you'd normally see something like

open ("fred") || die

which translates to

if (not open("fred")) then die

If you look at the assembler, in both cases, it is exactly the same.

We had such discussion in the eighties when programmers wanted to be artists, writing unreadable code just to be irreplaceable.
If you would be one of my programmers I would fire you immediately for this waste of money and time and delivering error-prone code. I thought those times were gone! Dead | X|

heh, i wasn't here for awhile Smile | :)

actually, ye're wrong on that: readable codes are good, only if you have no the needs of deep optimizations. deep optimization means vast asming.

Code can be both: Optimized and readable. It's just depends on the plannings. Cryptic code isn't any faster than good, optimized readable code. It's just harder to understand and correct. That's all.

Okay. I talked about higher languages. If you write asm codes, I won't mind if you code another way. Roll eyes | :rolleyes:

Without a doubt, that's the worst idea I've seen in a long time. Instead of using a nice, easy to read if, you've turned it into a very-expensive-to-support-and-debug piece of crap that you'd have to throw unit test after unit test at with a crap-ton of edges cases. Congratulations!

Now go back and wipe that smiley face off your post before I smack it off.

Spurious use of goto...

A true gem...

If CurrentContext = "D" Then GoTo c45

GetUserDataRecord aForm

c45:

There were no other ref's to c45, so replaced by...

If CurrentContext <> "D" Then GetUserRecord aForm

Further down in same procedure:

    GoSub ResolveTabOrder

    ' Other code here

    Exit Function

ResolveTabOrder:

    If uControlNbr < 2 Then Return

    ' More code here

    GoTo ResolveTabOrder
End Function

Just came across a [view name].[column name] combination in some SQL code I'm working with that is that many characters long. Actually, if it included the square brackets, it'd be 81 characters. Cry | :((

Here it is (characters changed to protect the guilty):
