Code:

struct Star
 r dd ?
 g dd ?
 b dd ?
 dist dd ?
ends

How do I declare array of above structure?
stars Star 10 dup <>
Doesn't seem to work Sad

Maybe this way:

Code:

stars rd 10 * (sizeof.Star/4)

Kludgey! But Works!
Isn't there a more direct, simpler way?

Code:

repeat 10
  rb sizeof.Star
end repeat

There isn't an array concept within the FASM language. MASM tries to fake an array concept with DUP, but initialization of multi-dimentional arrays is broken in MASM. It is better to leave the implementation of arrays to the programmer, imho. This greater flexiblity does add to the learning curve, but once you get to 0.2 you'll be glad the options are all open.

Note that actually does exist dup in fasm, the problem is that the win32 headers does not "overload" it to support structures defined with the struct macro.

hmmm, would be so hard to implement it? I gonna give it a try but don't expect much Razz

Loco: main problem will be, of course, that you can't overload operator in FASM

But I can match the macro argument and react accordingly. However I don't understand why match is not working inside the struc, even if I do "match times =dup (values), 10 dup (5)" it doesn't match while it matchs perfectly when I test it outside Confused

I will try more before posting something.

you must be messing something, matching inside struc works:

Code:

struc XXX arg
{
  match =special, arg 
  \{
    display 'oh yeah'
  \}
}

foobar XXX special

maybe it's because you use reservered word "times" as name of match argument?

No, just because I'm stupid. I've misplaced the "display 'reachable?',13,10" so I believed that the sub struc was overriding the one generated by the original headers but NO, so the match wasn't ever processed by the preprocessor.

Seems that I need some rest before continuing Smile

[edit]After my dinner I realized what is the problem but now I'm lazy to finish it Razz

Tomorrow (GMT-3) I'll post the code[/edit]

Vinita, try this:

Code:

proc        X

       ; Local table of 10 copies of 'Star' structure.
   ;
   local stars[10]:Star

        ; Some code.

    ret
endp
