Re: Big Crunch and not a Big Bang.
IMHO it is all pie in the sky. We create physics to rationalize Earthly events so we can use them to make our lives easier. We used to say "the laws of physics apply everywhere", so we ludicrously look into the cosmos and apply our physics there. Because our maths system is basically a cou...

Thanks Berkeley, plays well.
On reflection, 76 trombones might be apt also this year.

To keep the value of n intact you should use: Type WW ' nn As Long Declare Constructor End Type Constructor WW nn = 100 End Constructor Function MyFun() As ww Dim n As ww If 1 = 2 Then function= n 'Intentionally causing the function to not execute and return End Function for i As Long = 1 to 10 Prin...

Re: Rnd6 for Windows
I note rand_s is in msvcrt.dll.
Pity it cannot be seeded, or BCryptGenRandom cannot be seeded, although deltarho's Rnd6Repeat goes half way there.
Thanks srvaldez.

Re: FreeImage linking problems
If you call a dll at compile time (usual way), the easiest method is to put the dll in the same folder as your source code and include the .bi file which will call by #inclib and immediately find it. If you call at runtime with dylibload/dylibsymbol then you can use the the path to your dll, (... Fr...

Re: Happy birthday dodicat
Thank you everybody.
demosthenesk, your tune sounds good here.
Lothar Schirm, your moonlight shadow plays OK here on Win 11.
The crt.bi has _beep, which plays demosthenesk's tune just fine, using the arrays in the same way.

give me a few days to arrange things No problem I bought UK power plug adapters for the german powerline. Meanwhile I played with an (online) Acorn Electron emulator and the BBC BASIC is much powerful as the microsoft C64 BASIC. I love how simple you can mix the two pass 6502 assembler and BASIC co...

Re: Fast copy of all the bytes in a ubyte ptr to a string ??
'FB_memcopy()' (or 'memcpy()' ) is a very optimized copy procedure, about 25 times faster than a byte-by-byte copy like the one above. I did check the speed with a very large array, and it is very fast for bytes. Try the array at 1000000 64 bit fbc .002 sec and if I optimize with -O3 optimization, ...

Re: Fast copy of all the bytes in a ubyte ptr to a string ??
If you don't want to use files, then a custom sub could do the job. (similar to memcpy or fb_memcopy) randomize Sub CopyToString(dest As Any Ptr,src As Any Ptr,size As Long) Dim As Ubyte Ptr newdst=dest Dim As Ubyte Ptr newsrc=src While size size-=1 *newdst=*newsrc newdst+=1 newsrc+=1 Wend End Sub #...

Using files, as you suggested, with a ubyte pointer with size to string #include "crt.bi" Sub save(filename As String,apointer As Any Ptr,size As Ulong) Dim As file Ptr f = fopen((filename), "wb") Dim As Ubyte Ptr ap=apointer fwrite(Cptr(Typeof(ap),ap),size,1,f) fclose(f) End Sub...
