I'm 39 and work as an IT consultant (A glorified title, I just fix computers) in a factory and run a mom&pop computer store. I've been programming in BASIC for more than 25 years (began with a Spectrum 48K), mostly little things. I'm not a project man, I just fix little things.
I recently began to play with Android (I wish someday we would see FB to compile programs for it) and Arduino.
I'm also pleasantly surprised that many of you are in my age group also.
Cheers.

i turned 27 a couple weeks ago. i started using BASIC in the late 80's when i was a kid. i can do C and assembly now, but sometimes i just get the itch to do some BASIC coding.

I got a dozen beginner's C books, and I'm going to snag a Borland free C IDE and compiler package.
I'm looking forward to learning C finally.
I thank FB for demystifying C to me, because alot of the concepts that were absent before FB, have bridged the way for me to learn C now.



~Kiyote!

Crazy.
I missed the boat when the Commodore books went the way of C books.
I missed the boat when someone at a BBQ told me about the "Internet" when I was hooked on dial up BBS services.
I don't wanna miss the boat this time, with Android.

On the subject of old stuff, and old programmers, myself included, how many of you used BBS services, and what was your experience like?
What did you learn, what did you love, what did you hate, did you WRITE any of your own?
Can WE write some in FB using UDT or TCP?



~Kiyote!

<.< I want to have a BBS server program so bad, as close to an original BBS style as possible, with ANSI, RIP and ASCII graphics, including some easter eggs like OpenGL 3D.

Pretty and Interesting dodicat, but it's not very elegant at the end to finish the loop 'For' by an "out of bounds array access at line 124" (array: bar ()), for people who compile with option -exx.
I proposed this amendment:
for x as single=0 to xres - 1 step xres/(d)

Hi fxm ~ strange.
I compile now with -exx, since our silent altercation of a few days ago.
I made especially sure that that bleeding array never got out of bounds, I checked the value of count and it terminates at the array upper bound.
No error here.

Hi
I'm 21, and i'm a hobbyist Fb programmer. I will be working as a software engineer soon. I like to code little snippets here and there and games are my favourite area. I started Fb in 2006 i think, back then i had my little p3 ;p

Hi kiyotewolf
the -exx compiler switch is a strange fish, it is supposed to report errors including array out of bounds, well it does, for some arrays and different people.

In a loop 'For', it is preferable not to use floating iterator when the expected number of occurrences is important, because it may depend on rounding:
for x as single = 0 to xres step xres / d

In a perfect world, we should get d+1 values of x:
x = 0
x = xres / d
x = 2 * xres / d
x = 3 * xres / d
. . . . . . . . . .
x = d * xres / d
is one to many
but depending on rounding, you may obtain only d values of x.

I propose you to replace:

Code: Select all

dim count as integer
for x as single=0 to xres step xres/(d)
  count=count+1
  draw string(x+5,yres-20),str(bars(count))
  line(x,yres)-(x,0),rgb(0,0,0)
next x
by:

Code: Select all

for i as integer = 0 to d - 1
  draw string(i * xres / d + 5, yres - 20), str(bars(i + 1))
  line(i * xres / d, yres)-(i * xres / d, 0), rgb(0, 0, 0)
next i

@dodicat

Oh wow, I did not know that the -exx switch shows array out of bounds illegal accesses, do you have to compile with a console window to see all that error message stuff, or just direct the output of the compiler to see it, (aka read the error window in FBEdit.)

Does it show you pointer access illegal out of bounds errors to, say when you use the [] and * nomenclature?
