Is there a way to do something similar to

var = 234
db "1var5"

and have it output "12345", without using some slow ITOA macro that'll make it take forever to compile if I use many of these?

how about:

Code:

var equ "234"
db "1",var,"5"

Code:

macro itoa var
{
  display "1",`var,"5" ;debug
  db "1",`var,"5"
}

itoa 234

Let me post my exact code okay and tell me why it doesn't work together please

Code:

struc edb[a]{ common
                      . dd .len
                   label .data byte
            forward
                     local l,b
                   done equ
                    match =reverse b, a \{
                        done equ 1
                  l db b
                      repeat ($-l)/2
                              load b1 byte from l+%-1
                             load b2 byte from $-%
                               store byte b1 at $-%
                                store byte b2 at l+%-1
                              end repeat
                  \}
                    match , done \{
                               db a
                        \}
            common
                      .len = $-.data}


MrString        edb 'Hello, I am ',`MrString.len,' bytes long. In otherwords, ',`(MrString.len*8),' bits.'

It fails to compile with "value out of range"! Sad

Please, tell the value of MrString.len that you have calculated. It this equation possible to solve? I believe there are several correct answers, but haven't worked it out.

Expected output:

Code:

MrString.len      = 51
MrString.l: dd MrString.len
MrString:        db 'Hello, I am 51 bytes long. In otherwords, 408 bits.'

It would solve it by counting how long the string is, inserting the count into the right spots, and then recounting until the number stops changing, I guess. Or maybe it has a more optimized way.

# and ` must be used in a macro.

Eh, should work in a struc too.

So if I put it in a dummy rept or irp block it should work? It doesn't. Sad

Any other ideas?

I can't get it to interpret MrString.len as a number - always a string.

Adding:

Code:

display    13,10,`.len,13,10

..results in: MrString.len
Confused

(Even in Madis731's example above the macro argument is a string.)

That wouldn't work anyways.. I need to be able to put it anywhere in the string, not in a hard coded location x_x

Thanks anyways though

Well, when testing we might try other things to discover.
(I wasn't implying this was a solution to your problem.)

The manual says ` quotes a string as well.

I suspect the macro invocation is stripping the ` as well. Sad

(Put as many as you want and they are gone: ````````MrString.len)

Aww

Is there a way to fix this besides making more changes to FASM's source? I'm sick of having to change it.. and then re-apply all my changes to it every time a new version comes out..

Please???????
