Jeroen Jeroen Starting to like KiXtart Registered: 2001-08-16 Posts: 180 Loc: Netherlands	Hi Guys, Tell me - am I going crazy? Code: Cls Break on At (3,3)"Test1" Get $ Exit $null = MessageBox("TEST","TEST",4160) I would expect this code to generate "Test1" as output to the screen, and then to exit the script after I press a button. Instead, it also shows the messagebox... ?? If I change the code to: Code: Cls Break on At (3,3)"Test1" Get $ Exit At (4,3)"Test2" Get $ $null = MessageBox("TEST","TEST",4160) Then it does exactly what I would expect: output only "Test1" to the screen and exit. _________________________ Regards, Jeroen.

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	no, you're not going crazy you simply miss the exit code, whih causes the next statement to be executed: Code: Cls Break on At (3,3)"Test1" Get $ Exit 1 $null = MessageBox("TEST","TEST",4160) _________________________

Jeroen Jeroen Starting to like KiXtart Registered: 2001-08-16 Posts: 180 Loc: Netherlands	But the exit code is optional isn't it ? _________________________ Regards, Jeroen. There are two ways to write error-free programs. Only the third one works.

Jeroen Jeroen Starting to like KiXtart Registered: 2001-08-16 Posts: 180 Loc: Netherlands	Or at least, that is what I understood from: "If EXIT is followed by a numeric expression, then @ERROR is set to the value of that expression and you can check it in the calling script or batchfile." _________________________ Regards, Jeroen.

Richard H. Richard H. Administrator Registered: 2000-01-24 Posts: 4946 Loc: Leatherhead, Surrey, UK	Short answer - no, it's not optional. Also applies to QUIT. Don't believe the manual, it tells half-truths. Long answer - yes it is optional BUT in some cases the code following the Exit will be interpreted as the optional parameter. This is because KiXtart is a free format language and newlines don't have any special meaning so the first bit of code on the next line becomes the parameter. When this happens the code "disappears". I think we may have a FAQ for this, it used to come up a lot usually with misbehaving conditional constructs. Exiting without setting a status is a really bad habit anyway, so consider it mandatory. [edit]Found the FAQ, getting a bit long in the tooth but here it is: http://www.kixtart.org/forums/ubbthreads.php?ubb=showflat&Board=5&Number=130059 [/edit]

Surely, unless you want to exit a program with an error code, then the RETURN command is the best to use. (I also remember the 60s, and I know I was there). _________________________ Bill

(I also remember the 60s, and I know I was there). Yes, you could use RETURN to avoid setting the exit state but generally in coding circles it's considered a bit gauche, some compilers will even take you to task for such a willful breach of etiquette. It's good manners to explicitly set your exit state, and it takes as much typing to "EXIT 0" as it does to "RETURN" so there is really no excuse $\:\)$ Joking aside there are sound reasons for getting into the habit explicitly stating your error state when leaving a section of code, even if you don't think that it's important at the time.

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4402 Loc: New Jersey	Just a small technical clarification, Richard... It actually takes one LESS keystroke to type "Exit 0" than it does to type "RETURN" (5 vs 6). $\:\)$ I'm not sure if Return would work (properly) from a function, as it is used to exit from a subroutine.

I think when Robin Williams coined the phrase, the connotation was that if you were "there", you were smoking pot and everyone knows pot destroys your memory. I remember the 60's so I wasn't really "there". Back on topic, I agree with Richard that the Exit code should be set. _________________________ Give a man a fish and he will be back for more.
