Unlike FB, Visual Basic (up to 6 at least) and Qbasic, will give an error on arithmetic overflow, as opposed to saturating or wrapping. While this is useful for catching many bugs, I’ve often looked for workarounds to avoid triggering it. With 16-bit numbers, this isn’t as hard, and I think the best...

Hi robert, sorry for the delay.
I think you've used the wiki before as RoBert? I'm going to resurrect that account with your requested password hash.

Hi basicjohnny, thanks, I've added you to the wiki. Please set a secure password once you log in.

Thanks for your report.. Is it just new topics, or any topic?

Thanks for the report.
Note: the documentation files are produced from the FreeBASIC Wiki. This particular page is at /wiki/CompilerOptw.
From the history, it looks like Jeff corrected this last year.

The simplest workaround for this is to pad the string with enough Null characters (i.e. 'Chr(0)') to make sure the string is long enough.

I happen to have a copy of the archive downloaded from this thread, which was, I am pretty sure, PCEM_FB486.rar. I've uploaded it as a Github repo: https://github.com/countingpine/PCEM_FB486 I couldn't find any copyright information in the archive. I was going to add copyright info from version 0.41...

I've drafted some drop-in replacement fread/fwrite functions for the rtlib: static __inline__ size_t fread_large( void *ptr, size_t size, size_t nmemb, FILE *stream ) { size_t total = 0, nread, nchunk, shift; if (size < 1 || nmemb < 1) return 0; /* read at least 1MB of items per chunk */ for (shift ...

Hmm, looks like it might be a bug not in FB itself, but in Windows fwrite(): https://stackoverflow.com/questions/18694889/c-fwrite-binary-file-bigger-than-4gb/18694929#18694929 https://brucebcampbell.wordpress.com/2014/07/15/4gb-c-standard-library-fwrite-limit/ We use it in https://github.com/freeba...

I suspect there may be a (signed?) 32-bit overflow somewhere, if 2GB is not working. Here's a function that writes a pointer in 1GB chunks. function putptr(p as any ptr, size as longint, count as longint, handle as integer, position as longint = 0) as integer if count <= 0 or size <= 0 then return 0...

I think it’s enough to say that with variable-length strings, the descriptors are swapped without reallocating any string data memory. And for UDTs, the contents of the structures are swapped without any operators or methods being called. I don’t think it is worth discussing efficiency. The semantic...

As far as I know, there are no cryptographers or reverse engineering experts on the forum.. Compiled source code is a powerful obfuscation barrier, but an expert would probably be able to estimate a reasonable timeframe for cracking that step. If you truly want to know how secure it is, share the al...

There seems to be a forum of sorts for the Night Kernel at https://groups.google.com/forum/#!forum ... dos-kernel

Wow, that's pretty cool.

What does the effect do? Is it giving a Z coordinate based on the colour value?

Thanks for your update, xlucas. It's good to know this is a formally studied type of sequence, and there's at least one method of reliably generating them. I made a version based on the sample Python code on the Wikipedia page. The alphabet and the subsequence length are adjustable as constants: con...
