Including selected bytes from binary files using ACME
Looking for the proper way to include every 4th byte from a binary and put all the included bytes next to each other in the memory (Using ACME).
If the binary contains the text "commodore 64 computer", I would like to have this to appear in memory "coe pr".
I am currently doing it with a for-loop using !bin and counters, but the compiler report generates a very long list drowning the important messages in it.
I know I can save the memory range with a monitor to another binary, which then can be included in another assembly run to get rid of the long list, but this must be possible to achieve with a clever macro to just include the file once and then take the desired bytes from it.
Please point me in the right direction and if possible include a bit of code. Thanks! |

I simply add a _Step 4_ to my VB precalculator in such situations. Ppl want to do everything at compile time these days. |

why not simply put your loop thingy in a seperate asm file, assemble it and then include the resulting binary? i dont think acme can do what you want in a more compact way (and why should it really) |

Thanks for reading and the responses.
I was afraid it would be something like that, but I figured I ask the pros before giving up the idea or reinventing the wheel again. I hoped it would be possible to pre-arrange the data before actually putting it into memory upon include.
I will run a routine on init that will arrange the data as needed instead. |

Consider KickAss then, maybe it suits your style better. |

!for .x,0,49 { ;will do 50 runs
!bin "penis.bin",1,.x * 4
}
Throwing no errors or warnings here and all is fine? So where's the problem? |

Bitbreaker: I am doing a loop like that. The problem is not getting errors, but rather the feedback from the assembler as it includes files. Everytime it includes a byte it will generate a line telling it put a byte in an address. This list becomes very long if you include 1k of data this way.
I have generated two screenshots to explain what I mean, one with the loop and one without.

The only way I have found to avoid it is to either have the binfile already provided to the assembler in the right format, or do like the ostrich and set the verbosity level to 1 for Acme (meaning it won't show the actual addresses for any includes at all).
Anyway, I have prepared the datafile itself now as Groepaz suggested so it can be included with a separate include. Still bothers me somehow to use a workaround like that, but at least it gets the job done.
Thanks! |

just remove the -v3 from the acme command line, problem solved. |

Really, use your favourite scripting language to create an intermediate file and include it with one line.
Sprinkle some Makefile magic on top to avoid unnecessarily rebuilding that file on every compile run.
As Oswald said, why do everything in your source code? If you really need to, use another assembler which was made for that paradigm, like the proposed KickAss. |
