Hi,
Since when did FASM start checking for running instances - its rather annoying when all my files open up in one window as tabs. I want to keep projects in separate windows, because I can't tell FASM which files go with which project Sad

I didn't find any new flags that I can tick. Btw, FASM 1.66 doesn't have this problem and so I make use of this when I want to open more instances.
Will it be reverted yes / no / that's my own fault?

Second one is about using struct:

Code:

struct IHDR
    length rd 1
    width  rd 1
    height rd 1
    bitdep rb 1
    coltyp rb 1
    commet rb 1
    filmet rb 1
    intmet rb 1
ends

someone might recognize the PNG there Smile

Using this is in fact very easy:

Code:

    ;esi points to the beginning of a PNG-file
    mov     ecx,[esi+8]                 ; Length of header
    bswap   ecx
    mov     [ihdr.length],ecx

The problem is that the addressing mode is too long and I would like
to make it register-based:

Code:

    mov     edi,ihdr
    mov     ecx,[esi+8]                 ; Length of header
    bswap   ecx
    mov     [edi+ihdr.length-ihdr],ecx

Oh that horror Sad

edi=ihdr so its comes out pretty pointless:

Code:

[ihdr+ihdr.length-ihdr] ;  heh
;of course .length is not defined:
[edi+.length] ; an error

My question is if there is a more elegant solution or maybe somehow I can
tell ihdr.length that its not absolute, but ihdr-based ^o)

Thanks

All I can do about it is maybe an option to create a new instances.

First of all, I'd recommend reading carefully the docs.
And look also here: http://board.flatassembler.net/topic.php?t=1905
(and maybe also here: http://board.flatassembler.net/topic.php?t=4893 and here: http://board.flatassembler.net/topic.php?t=4612).

The aswer was there Very Happy

- if I only had looked more carefully. At first I didn't understand the "carefully"...
...I need to point to the structure NOT the instance of that structure Razz

Sorry!

You can still create a specialized instance for the register-based addressing, however it seems people are not so enthusiastic about this feature. Wink
