This ChooseColor API troubled me for a day, and I finally found the answer. It turns out it was a data structure issue. Thank you very much!

I agree on annoying spaghetti code,gosub 2000 for example but compiled its might instead hidden on different call memory address 2000 instead
Small text has pre computer solution : reading glasses,but if you are lucky someone has scanned in all old computer magazines that had basic code as PDF
Edit
I don't know if archived compute magazine have any basic game of interest ?
Copy and paste code simpler than tedious type in basic code in editor ?

Well, that book has seventy to eighty odd more of the same ilk.

It was actually a short period before structured BASIC arrived, but long enough to destroy BASIC's reputation forever.

Hi Jochen,

I must say that the *.bas code is a really ugly example of spaghetti code - it hurts the eye.

   Well, that book has seventy to eighty odd more of the same ilk.
Not to mention using rather small text.  That hurts my eyes.

Cheers,

Steve

16 bit DOS Programming / Re: Line Drawing

Last post by FORTRANS - May 20, 2024, 10:19:28 PM

Hi Tim,

In any case, I think my next step is to treat each quadrant in its own routine and to get that working.

   The last time I tried coding a general purpose line drawing routine,
I wrote code for the four quadrants, horizontal lines, vertical lines,
and the two diagonal lines.  Those last four could be coded up rather
easily, and could be faster than a general purpose line drawing routine.

Regards,

Steve

Edit:   With the four special case lines, it should be eight octants, not
four quadrants.

 hMod = LoadLibrary("kernel32.dll");


this statement might return NULL
so not checking for this might hard hit the app...
just in case :)

PS I know the chance of getting NULL is 0.0001% but who knows

MasmBasic & the RichMasm IDE / BASIC: ON someval GOTO line100...

Last post by jj2007 - May 20, 2024, 09:58:56 AM

Just for fun, and inspired by Steve's GW-BASIC thread, I made two new macros mimicking BASIC's ON someval GOTO 100, 200, 300 command (ecx is the index):

Code Select Expand

.code
p0:
  deb 4, "P0", eax
  retn
p1:
  deb 4, "P1", eax
  retn
...
g0:
  deb 4, "G0", eax
  jmp @back
g1:
  deb 4, "G1", eax
  jmp @back
...

  For_ ecx=0 To 2
    lea eax, [ecx+100]        ; pass a value in eax
    OnIndexCall ecx, p0, p1, p2
  Next
  For_ ecx=0 To 2
    lea eax, [ecx+1000]        ; pass a value in eax
    OnIndexGoto ecx, g0, g1, g2
    @back:
  Next
Output:
P0      eax             100
P1      eax             101
P2      eax             102
G0      eax             1000
G1      eax             1001
G2      eax             1002

Source attached. ON ... GOTO ... is not the most beautiful command, but it can actually be handy.
