PC-BASIC
« on: November 25, 2018, 09:09:33 AM »
I found the software.

This software looks classic and nostalgic.




This software may be suitable for kids to learn programming because of a comprehensive manual.

The creator of the software has created a true masterpiece.

I was kind of happy when I found this basic (here linked) Appearantly it was supplied with the playstation 2 for some kind of tax break.

The more recent fantasy consoles look kind of interesting also. I have pico-8 from a humble sale and there is a free (basic8) console on the windows store.

You have to love just how far BASIC has got itself... incredible achievement :)

Although BlitzMax is not exactly BASIC per se, it does have it's foundation squarely built upon BASIC so here's a quick, hacked up BlitzMax port of the demo that's on the first page on the yabasic link from Pakz.

Code: [Select]
Strict

SetGraphicsDriver GLMax2DDriver()
Graphics 640,512

Global size:Float = 12
Const points = 8
Const faces = 6

Global dw
Global x[points], y[points], z[points], tx[points], ty[points], tz[points]
Global f1[faces], f2[faces], f3[faces], f4[faces], r[faces], g[faces], b[faces], Cls_[faces]
Global cs:Float[720], sn:Float[720]
Global xr:Float, yr:Float, zr:Float
Global starcount = 100
Global star_x[starcount], star_y[starcount], speed[starcount]
Global style
Global wp, wip:Float

initialise

Repeat
  Flip
  Cls
  If style = 0 stars

rotate
construct

  If style = 1 stars
  ' Make Cube Move
  If wip <= 0 wp = 0
  If wip >= 5 wp = 1
  If wp = 0 wip = wip + 0.05
  If wp = 1 wip = wip - 0.05
  ' Zoom In / Out
  If (size < 24 And KeyDown(KEY_E)) Then size = size + 0.5
  If (size > 1.5 And KeyDown(KEY_D)) Then size = size - 0.5
  ' Change Style
  If KeyHit(key_k) style = 1 - style
Until KeyDown(key_escape)


Function stars()
  For Local i = 0 Until starcount
    star_y[i] = star_y[i] + speed[i]
    If star_y[i] >= 512 Then
      star_x[i] = Rand(640)
      speed[i] = Rand(3) + 1
      star_y[i] = 0
    EndIf
    SetColor 80 * speed[i], 80 * speed[i], 100 * speed[i]
    Plot star_x[i], star_y[i]
  Next
EndFunction

  For Local a = 0 Until faces
    draw(a)

Hello,

I try to look for information of Pico-8 and BASIC8 after reading your introduction post.

"PICO-8 is a fantasy console for making, sharing and playing tiny games and other computer programs. When you turn it on, the machine greets you with a shell for typing in Lua commands and provides simple built-in tools for creating your own cartridges."
https://www.lexaloffle.com/pico-8.php

"BASIC8 is an integrated Fantasy Computer for game and other program development. You can create, share and play disks in a modern BASIC dialect, with built-in tools for editing sprite, tiles, map, quantized, etc."
https://paladin-t.github.io/b8/

Both softwares are similar products. They are very innovative tools. Thanks for telling our members and me these two fascinating programs.   ^-^
