I would like to define, say, 5 symbols:

Code:

pos1 = 2
pos2 = 4
pos3 = 6
pos4 = 8
pos5 = 10

Can I do something like:

Code:

repeat 5
    pos#%# = % * 2
end repeat

I looked up ` and # symbols in fasm manual, but could not understand the correct combination to work this out.

For some reason that repeat block causes "illegal instruction" error, but does not when is inside a macro block.

If I'm not wrong, concating of symbols as this are only allowed inside macros...

Well, it still does not work even inside macro.

Same with symbol < and >. I find it useful to use them outside macros sometimes.

Code:

macro foobar name,value {
    pos#name = value
}
repeat 5
    param = %
    foobar param,%
end repeat
display posparam+30h,13,10

This define posparam 5 times, finally making it equal to 5. Looks like FASM just pass by reference in macro, not value?

macro IdNum strt,[equat]
{
common
local count
count = strt
forward
equat = count
count = count + 1
}
IdNum 1,\
IDM_NEW,\
IDM_OPEN,\
IDM_SAVE,\
IDM_EXIT,\
IDM_ADD_TO,\
IDM_CLOSE,\
IDM_DIALOG
It creates 7 macro variable. You wanted it to achieve?

Here's my try

Code:

macro foo name,first,[list]
{       common  local counter
                counter =  first
        forward name#list = counter
                counter = counter + 1}

nums    fix .1,.2,.3,.4,.5,.6,.7,.8
foo pos,1,nums

;or
;foo pos,1,.1,.2,.3,.4,.5

display pos.2+30h,13,10
display pos.5+30h,13,10

------
BTW, # directive outside maros would be really handy sometimes

Spasibo!
That is almost it, because num has to be variable though.

Yes, it will. Also this outside macros:

Fasm Manual wrote:

When it's needed to provide macroinstruction with argument that contains some commas, such argument should be enclosed between < and > characters. If it contains more than one < character, the same number of > should be used to tell that the value of argument ends.

i.e.

Code:

mov eax,<'a',09h,'1'>
cmp dx,<'b',0>
