Assembler preferences.
Two questions:
- what's everyone using these days?
- on large productions, do groups tend to enforce a single assembler for the entire project, or is the code base a bit heterogenous?
I'd like to keep this discussion purely focussed on assemblers; please leave code generators, loader toolchains etc for that other thread.
(as for me, I'm still using xa65 for most projects) |

Fungus: I'm not sure what you mean, at least what I think of is quite old. Unless I misunderstood the question.
The built-in "size()" function returns the length. The .logical/.here (pseudo pc stuff) is a "transparent" code block. You can access this block by defining a label at it's start, and it's size is probably what you're looking for.
stuff .logical $300
nop
.here
.word size(stuff) ; length of .logical/.here
ldx #size(stuff)
It's also mentioned in the "Usage tips" section of the manual in an example for copying zeropage code to it's final place. |

@enthusi: I think you should give current ACME a chance, as most (or even all) of what you complain about has been realised inbetween. Of course you might need to "learn" a few tokens.
As for
Quote:automated filling and shit *g*
there is
!fill,<no. of bytes>,<fillbyte>
to determine yourself which range to fill with what
plus, there is
!initmem
to make clear how "empty" areas not specified via !fill are supposed to be filled (zero by default if you do not use !initmem)
I can only tell you, ask Mac Bacon, whenever sth is unclear or you want sth to be improved. My experience is, he's a true genius but also a really nice and helpful guy, who always replies quickly or - if you convince him sth is worth improving - even updates ACME in next to no time. |

yes, I believe all of that :) While back then I had a reason to change, I do not have one now, though. XA feels more 'raw' which is what I prefer in fact. |

so what does initmem do ? why should the assembler know how memory looks like ? I dont get it |

* = $1000
nop
* = $2000
nop
what should go to $1001-$1fff ? -> initmem |

Ah yes, that's exactly what I meant. I was still doing it the old tass way with using calculations :)
hrm... we need wiki's for these things. CSDB needs a wiki system :D |

Calculations are fine if you don't mind a second symbol.
There's codebase64, so I think we have a wiki already. |

I meant a wiki in general dedicated to use of tools and what not. :) |

There is already codebase64 wiki but page about cross tools is terrible outdated - just like many other parts of this great site - for example it provides link to long gone ACME homepage. Wouldn't it be better if try to update codebase64 instead of creating another wiki? |
