Thanks Slammer!
Your solution is much more elegant than mine!
It's a shame that I haven't noticed this in the documentation. :) |

From my -PNGtoKOALA routine I get the following error:
.for (var Pixel = 0 ; Pixel < 4 ; Pixel++) {
.eval PixelColor = Graphics.getPixel([[8*BlockNumber]+[[Pixel<<1]&7]]-[320*[floor(BlockNumber/40)]] , [8*floor(BlockNumber/40)]+Byte)
.eval BMPPattern = ColorIndex.get(PixelColor)
.eval BMPByte = BMPByte|[BMPPattern << [6 - Pixel*2]]
^
Error: Unknown function : <<
I've used it before and it worked fine so what the heck am I missing?
EDIT: Found out. Had some "ghost pixels" with different RGB codes in the GFX I was converting... Funtion works as intended. SOLVED. |

BMPPattern contains a value for which the << operator is not defined. Could it be null? |

Any update on .ifdef/.ifndef directives? Would be very handy. |

The basic directives are implemented as know from C# (#define, #if, #else, #elif, #endif, #undef). Currently missing is setting definitions from the commmand line and boolean operatiors. But they will be there, don't worry.
Other nice things which are already implemented are:
- The * is back, *=$1000. (You can still use .pc)
- You can now use normal ( ) aswell as [ ]
- You can add an optional ; in the end of commands, eg: .eval x=27;
+ Some other goodies
The reason it takes time is that they are part of a bigger modification, where the entire parsing routine is reimplemented. Instead og using a parsergenerator, most of it is now done by handwritten code which gives more flexability. This will be in the next major version (4.0). I guess it will take at least a couple of months finish. |

Is anyone else having problems after updating OSX to El Capitan? On Build & Run everything works fine except that Vice exits immediately after it starts. Any tips how to solve this? |
