Current master version on github

https://github.com/paulrho/ijk64/raw/master/C64.jar

Run

From Command Prompt or Terminal...

java -jar C64.jar -c -2

(Centered and double pixel size)

Use

Load a directory listing from the (cloud) web... (currently shared)

HELP
LOAD"%"
LIST
LOAD"%GENES2016"
RUN

Right click on screen for a context menu

Tips

For CTRL key use Tab
For C=   key use Left-Ctrl
For RUN/STOP key use Shift-Esc

Run with proxy:
java -Dhttp.proxyHost=111.222.111.123 -Dhttp.proxyPort=8080 -jar C64.jar

Run faster (initially runs slower, then runs nearly twice as fast)
java -server -jar C64.jar

Details

C64 paradigm:

Most C64 basic commands / functions
Some essential pokes

Transcending the C64 paradigm:

Screen

Allows for larger (and smoothed) characters, 1x1, 2x2, 3x3, 1x2 point sizes
Allows for larger (x,y) screen characters (e.g. 80 x 80 chars)
Screen buffers as writes
Fine tuning of background etc

Mouse / Keys

Click move cursor to point
PgUp/PgDown Scrollwheel look back/forward in buffer
Righ click menu
Auto-insert switched on by default (switchable)
Copy whole screen
Paste into screen
List
Syntax highlighting (switchable)
more than 2 lines allowed

Language

Extra graphics mode and commands (Hand Basic)
Meta commands to control screen size etc
Play sound (wav)

Machine

Much more RAM
Faster

Allows loading from web
Use ":" prefix shorthand to alias "http://www.futex.com.au/basic"
Runs in java, runs on a Raspberry Pi

New fixes & features

with 3.4.0.b1897

fixed: ascii-chr (internal character coding) and other ascii tweaks
fixed: allow CTRL (TAB) keys A-Z (on top of existing 0->9), and reverse lookups
fixed: ti$ to display hhmmss & special tisec to be seconds from epoch
minor : loading message change, allow load"*" = load"%"
fixed (allowed) windows format basic/txt files (CR/LF)
fixed (allowed) let def prefixes
fixed ; , spc and tab in print statements
changed cloud directory
merged for and gosub stack = one stack (keeps c= behavior)
fix: black text, error cr, outofmem for stack
fix data string (trim leading spaces)
fix chr$(160) block - not reversed
implement on goto/gosub
syntax highlight improvements
playsound and alert fixes
allow run# goto# from direct mode
fixed character mapping (pc<->c64)
keep cursor colour after listing
added NOT keyword, error when not used correctly e.g. A NOT B
changed precedence of -5^2 to match C64 (^ highest then -ve)
changed precedence of xor
experimental save/load from "cloud" - prefix filename with "%", e.g.
cloud directory listing
```
load"%"
```
load a file from cloud
```
load"%filename"
```

Code Architecture

To Do

* 160 isn't a reversed block (I think) =FIXED!- changed test case
* string after data token space = FIXED
* doesn't allow input"string";i$ - FIXED
* things ending in SPC() (or TAB()?)-FIXED
  is same as ;-FIXED
* ; then space then : or EOL-FIXED
* poke1024,160 : wont show unless space over it! (default color black!) -> see clear screen set colour
. let - done

-----
* when clear screen - should set colour to cursor colour (?)
* doesn't allow input c : (treats as string)
* exact 40 chars with ; - note sure this is an issue
* DATA/READ cant read data unless run already (should force a caching somehow)
* space between func name and ( (should be allowed but isnt')

** Feature completions:
*implement:
. go
. usr
. cmd

** Feature Expansions:
* required feature:  copy paste part of screen and full log
* required 128 expansions:
  * print using
  * else
  * begin
  * bend

* implement:
. Implement:
. Graphics: GRAPHIC, SCNCLR, COLOR, BOX, CIRCLE, DRAW, PAINT, LOCATE, SCALE; CHAR
. RCLR(), RDOT(), RGR()
. Sprites & Shapes: SSHAPE, GSHAPE, SPRSAV, SPRDEF, SPRITE, SPRCOL, MOVSPR, RSPCOL(), RSPPOS(), RSPR()
. COLINT, RBUMP()
. Inputs: KEY, RJOY(), RPOT(), RPEN()
. Music & Sound: TEMPO, TUNE, FILTER

Raspberry Pi

Unix, linux from the beginning:
Terminal (is the unix shell)
default userid is "pi"
# and everything after in shell is a comment
root is the master user with all permissions
sudo su   #will start shell as root user
sudo ..a command.. # will run that command only as root

Updating the software

sudo apt-get update       #updates the software list
sudo apt-get upgrade      #updates the actual software
sudo apt-get dist-upgrade #updates major versions
sudo rpi-update           #updates the firmware

To get this configuration LOAD"%PI":RUN
