Local 2D Array of strings crash (*solved*) - LTee - 11-16-2010 I seem to be having some issues trying to use a 2D array of Strings in some cases, but unfortunately I don't seem to be able to figure out what they are. A piece of code which seems to work fine in isolation fails when I put it into my main program with screen corruption and a crash. Is a 2D array of Strings 'bad form' for some reason? In the end I replaced it with a 2D array of UBYTEs instead which worked okay (and was probably less wasteful, tbh - I was only storing single characters anyway). If I figure out a decent way to reproduce the crash without it being embedded in a huge chunk of other stuff then I'll post it. It could well be something silly that I've done elsewhere in the program. ![]() While I'm here, could someone clarify what is okay to declare within a SUB? I don't seem to have any problems declaring normal variables (e.g. DIM test AS UBYTE) within a SUB, but I seem to have crash issues if I try to declare and use an array (e.g. DIM test(2,2) AS UBYTE). Is it actually legal to try and do that? This code, for example, crashes unless I move the UBYTE array outside of the SUB: Code: test() Sorry if the answer here is obvious, I'm still getting used to how things work. ![]() Re: Local 2D Array of strings crash - boriel - 11-16-2010 Since this is a different issue, I've moved it to a new topic :!: And yes, this is a another bug. :| Let me investigate it... Re: Local 2D Array of strings crash - LTee - 11-17-2010 Thanks, Boriel! Sorry for finding another bug. ![]() Re: Local 2D Array of strings crash - boriel - 11-17-2010 LTee Wrote:Thanks, Boriel! Sorry for finding another bug.No, thanks to you. :!: :wink: It seems fixed now. Please, download new version r1606 and test it. Re: Local 2D Array of strings crash - LTee - 11-17-2010 Thanks, I'll grab that now and give it a trial run later on. I'll let you know how I get on! Re: Local 2D Array of strings crash - LTee - 11-17-2010 Hmm... is the zip package not updated? I downloaded it and installed but it reports back as 1603 rather than 1606. Sorry to be a pest. ![]() Re: Local 2D Array of strings crash - boriel - 11-17-2010 Please, check it anyway. Version number is not updated automatically (a subversion problem I'm trying to fix up). So even if it reads 1.2.6-r1606 (or the whatever) it might be the last version. You can also update to the lastest trunk / developmnet with: svn update <!-- m --><a class="postlink" href="https://boriel.homeip.net/svn/zxbasic">https://boriel.homeip.net/svn/zxbasic</a><!-- m --> Current version is rev1666 Re: Local 2D Array of strings crash - LTee - 11-17-2010 Okay, I'll test it regardless. I'm don't think SVN will work through my company's firewall, but I should be able to do that from home later on if needs be. Re: Local 2D Array of strings crash - boriel - 11-17-2010 I'm not saying you to try the /trunk development/ version with subversion, but to run your program with the version you downloaded today. You can download it here: <!-- m --><a class="postlink" href="http://www.boriel.com/wiki/en/index.php/ZX_BASIC:Archive">http://www.boriel.com/wiki/en/index.php ... IC:Archive</a><!-- m --> Have you compiled it? Even if it has the same version number it's a *different* new one. Re: Local 2D Array of strings crash - LTee - 11-17-2010 Now that I've had a chance to look at the files a bit more carefully I can see that some of them are different to the previous version despite the version number being the same, so no problems there - sorry for the confusion! And the good news is that the bug appears to be fixed - I managed to compile and run the test program above (and some other ones that I didn't post) without any errors or crashes. Many thanks for your continued hard work, boriel! It's very much appreciated! ![]() Re: Local 2D Array of strings crash - boriel - 11-17-2010 Ok :!: Thanks a lot (this bug is marked as fixed, although I still have to make some changes in the compiler). :roll: |
