Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	Speaking of what feels right (not sure if this has already been discussed) did we ever come to a collective decision in terms of what constitutes a boolean TRUE ? -1 ? 1 ? For those that like to test absolute values. My suggestion would be that boolean true be whatever the NOT 0 expression resolves to. [ 01. November 2002, 19:48: Message edited by: Shawn ]

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	I started to think that boolean, and if it does not meet actual boolean definition, there is no actual boolean in kixtart. meaning that you can't create false and true in "normal" way. this in mind, as long as you keep the same rule all the way in the script, it will pass. _________________________ ! download KiXnet

kholm kholm Korg Regular Registered: 2000-06-19 Posts: 714 Loc: Randers, Denmark	Shawn, I aggree on this 0 (Zero / Nothing / or empty) is False Anything else is True This is already part of the general KiXtart syntax. An empty string is FALSE A Not defined variable is FALSE Return of an object from COM (GetObject/CreateObject) should alse be FALSE If the operation fails

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	I agree Erik, anything that is NOT 0 is true. FYI with COM, its generally recognized that when forced to specify a value for TRUE, everyone uses -1. Its interesting to note however that when Kixtart evaluates NOT 0, it returns a 1 (which to my mind, is intuitively a better TRUE than -1 is) and I think why this situation occured has more to with with the history and legacy of Kixtart more than anything else, even though the NOT operator was added late in the game (not sure really). I know that we're talking around isoteric issues here, but does it make sense to leave FALSE as an unspecified value that is NOT 0 ? Im cool with it because I tend to pratice poor coding habits anyways. Break more rules than I follow thats to be sure. The question really becomes, is a statement like this best pratice: code: if $bFlag ; then do something true else ; do something else false endif because that would be the impact of leaving boolean TRUE as un-specified. From what I've seen around this board, this kind of opened-ended if statement expression is frowned upon, fe: the best pratice version of above ? code: if $bFlag = 1 ; then do something true else ; do something else false endif [edit] lol - heres a quasi best practice variant: code: if not not $bFlag ?"true" endif I need some coffee.

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	this goes to the bone of kixtart. the freenes is to do: if instr("acb","b") it's instr and as such true, but kixtart also returns a value for that. so, it actually checks for true/false and location. this also raises the issue how well kix can have a hn specification as also: if "a" results in true. but, this is one of the strengths of kixtart and I would not go disturb this with standardation. _________________________ ! download KiXnet

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	yap - INSTR() is a perfect example of why NOT 0 is a great definition of TRUE. Maybe great is NOT a good word ... usefull would be a better word. I guess it could also be coded as: code: if instr("abc","b") > 0 ; ... endif all the more reason why I think a 1 is more TRUE than -1 is. And even more reason why Ruud should build TRUE and FALSE into the language (just like almost every other language one can name) ala: @TRUE and @FALSE macros. I mean, when coding a UDF that returns a boolean, wouldn't it be more convenient (and standardized) if we could just say this: code: return @TRUE Then for those that like to code both sides of the expression, they can just say this: code: if $rs = @TRUE ; ... endif [ 01.

So, a simple request evolves into a fascinating logic-fest, from which the consensus seems to be that False is False always, and True is True always, sometimes. _________________________ We all live in a Yellow Subroutine...

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	waltz, there is the best part! while coding with kixtart 1 can be 0 and vice versa. but, you should always remember that in the same code range it is what you make it to be. that is, unless you change it in the... one can always make code hard as simple old time sample tells: code: for $c=1 to 2 $c=0 next _________________________ ! download KiXnet

Les Les KiX Master Registered: 2001-06-11 Posts: 12734 Loc: fortfrances.on.ca	We like to joke about our short summers... Sombody asked "What are you doing next summer?" to which was the reply "Well, if it falls on a weekend maybe I'll go to the beach". _________________________ Give a man a fish and he will be back for more.

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	oh boy! that is short! we still have 3-4 month summer (meaning over 15 degrees celcius)... someone thinks that is not much, but live in country where winter is -50 celcius, even 0 seems like +30! _________________________ ! download KiXnet

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	rofl - Don Cherry's brown pops - it would be interesting to invite Don Cherry to this forum to give us his own take on the subtle flavours of TRUE ... I can just see it now ... "Ah jeez them booleans are a joke ... just make 'em zero or dat -1 thingy dare and get on with it eh ! whats da big deal dare eh ? It aint friggin rocket science ya know!" roflmao [ 01. November 2002, 23:19: Message edited by: Shawn ]
