Btw. One thing about the assert commands. They don't stop execution if they fails. Instead they remember the error and print them out at the end of execution (If no 'hard' errors occurs.) They are primary made so I could have a testsuite to run before each release (currently 615 asserts)
I guess this explains your original problem :-)

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? |
